mbed TLS ChangeLog (Sorted per branch, date)
|
|
|
|
= PolarSSL 2.0 branch
|
|
|
|
Features
|
|
* Support for DTLS 1.0 and 1.2 (RFC 6347).
|
|
* Ability to override core functions from MDx, SHAx, AES and DES modules
|
|
with custom implementation (eg hardware accelerated), complementing the
|
|
ability to override the whole module.
|
|
* New server-side implementation of session tickets that rotate keys to
|
|
preserve forward secrecy, and allows sharing across multiple contexts.
|
|
* Added a concept of X.509 cerificate verification profile that controls
|
|
which algorithms and key sizes (curves for ECDSA) are acceptable.
|
|
* Expanded configurability of security parameters in the SSL module with
|
|
mbedtls_ssl_conf_dhm_min_bitlen() and mbedtls_ssl_conf_sig_hashes().
|
|
* Introduced a concept of presets for SSL security-relevant configuration
|
|
parameters.
|
|
|
|
API Changes
|
|
* All public identifiers moved to the mbedtls_* or MBEDTLS_* namespace.
|
|
Some names have been further changed to make them more consistent.
|
|
Migration helpers scripts/rename.pl and include/mbedlts/compat-1.3.h are
|
|
provided. Full list of renamings in scripts/data_files/rename-1.3-2.0.txt
|
|
* Renamings of fields inside structures, not covered by the previous list:
|
|
mbedtls_cipher_info_t.key_length -> key_bitlen
|
|
mbedtls_cipher_context_t.key_length -> key_bitlen
|
|
mbedtls_ecp_curve_info.size -> bit_size
|
|
* Headers are now found in the 'mbedtls' directory (previously 'polarssl').
|
|
* The following _init() functions that could return errors have
|
|
been split into an _init() that returns void and another function that
|
|
should generally be the first function called on this context after init:
|
|
mbedtls_ssl_init() -> mbedtls_ssl_setup()
|
|
mbedtls_ccm_init() -> mbedtls_ccm_setkey()
|
|
mbedtls_gcm_init() -> mbedtls_gcm_setkey()
|
|
mbedtls_hmac_drbg_init() -> mbedtls_hmac_drbg_seed(_buf)()
|
|
mbedtls_ctr_drbg_init() -> mbedtls_ctr_drbg_seed()
|
|
Note that for mbetls_ssl_setup(), you need to be done setting up the
|
|
ssl_config structure before calling it.
|
|
* Most ssl_set_xxx() functions (all except ssl_set_bio(), ssl_set_hostname(),
|
|
ssl_set_session() and ssl_set_client_transport_id(), plus
|
|
ssl_legacy_renegotiation()) have been renamed to mbedtls_ssl_conf_xxx()
|
|
(see rename.pl and compat-1.3.h above) and their first argument's type
|
|
changed from ssl_context to ssl_config.
|
|
* ssl_set_bio() changed signature (contexts merged, order switched, one
|
|
additional callback for read-with-timeout).
|
|
* The following functions have been introduced and must be used in callback
|
|
implementations (SNI, PSK) instead of their *conf counterparts:
|
|
mbedtls_ssl_set_hs_own_cert()
|
|
mbedtls_ssl_set_hs_ca_chain()
|
|
mbedtls_ssl_set_hs_psk()
|
|
* mbedtls_ssl_conf_ca_chain() lost its last argument (peer_cn), now set
|
|
using mbedtls_ssl_set_hostname().
|
|
* mbedtls_ssl_conf_session_cache() changed prototype (only one context
|
|
pointer, parameters reordered).
|
|
* On server, mbedtls_ssl_conf_session_tickets_cb() must now be used in
|
|
place of mbedtls_ssl_conf_session_tickets() to enable session tickets.
|
|
* mbedtls_ssl_conf_truncated_hmac() now returns void.
|
|
* mbedtls_memory_buffer_alloc_init() now returns void.
|
|
* X.509 verification flags are now an uint32_t. Affect the signature of:
|
|
mbedtls_ssl_get_verify_result()
|
|
mbedtls_x509_ctr_verify_info()
|
|
mbedtls_x509_crt_verify() (flags, f_vrfy -> needs to be updated)
|
|
mbedtls_ssl_conf_verify() (f_vrfy -> needs to be updated)
|
|
* The following functions changed prototype to avoid an in-out length
|
|
parameter:
|
|
mbedtls_base64_encode()
|
|
mbedtls_base64_decode()
|
|
mbedtls_mpi_write_string()
|
|
mbedtls_dhm_calc_secret()
|
|
* net_accept() gained new arguments for the size of the client_ip buffer.
|
|
* In the threading layer, mbedtls_mutex_init() and mbedtls_mutex_free() now
|
|
return void.
|
|
* ecdsa_write_signature() gained an addtional md_alg argument and
|
|
ecdsa_write_signature_det() was deprecated.
|
|
* pk_sign() no longer accepts md_alg == POLARSSL_MD_NONE with ECDSA.
|
|
* Last argument of x509_crt_check_key_usage() changed from int to unsigned.
|
|
* test_ca_list (from certs.h) is renamed to test_cas_pem and is only
|
|
available if POLARSSL_PEM_PARSE_C is defined (it never worked without).
|
|
* Test certificates in certs.c are no longer guaranteed to be nul-terminated
|
|
strings; use the new *_len variables instead of strlen().
|
|
* Functions mbedtls_x509_xxx_parse(), mbedtls_pk_parse_key(),
|
|
mbedtls_pk_parse_public_key() and mbedtls_dhm_parse_dhm() now expect the
|
|
length parameter to include the terminating null byte for PEM input.
|
|
* Signature of mpi_mul_mpi() changed to make the last argument unsigned
|
|
* calloc() is now used instead of malloc() everywhere. API of platform
|
|
layer and the memory_buffer_alloc module changed accordingly.
|
|
(Thanks to Mansour Moufid for helping with the replacement.)
|
|
* Change SSL_DISABLE_RENEGOTIATION config.h flag to SSL_RENEGOTIATION
|
|
(support for renegotiation now needs explicit enabling in config.h).
|
|
* Split MBEDTLS_HAVE_TIME into MBEDTLS_HAVE_TIME and MBEDTLS_HAVE_TIME_DATE
|
|
in config.h
|
|
* net_connect() and net_bind() have a new 'proto' argument to choose
|
|
between TCP and UDP, using the macros NET_PROTO_TCP or NET_PROTO_UDP.
|
|
* Some constness fixes
|
|
|
|
Removals
|
|
* Removed mbedtls_ecp_group_read_string(). Only named groups are supported.
|
|
* Removed mbedtls_ecp_sub() and mbedtls_ecp_add(), use
|
|
mbedtls_ecp_muladd().
|
|
* Removed individual mdX_hmac, shaX_hmac, mdX_file and shaX_file functions
|
|
(use generic functions from md.h)
|
|
* Removed mbedtls_timing_msleep(). Use mbedtls_net_usleep() or a custom
|
|
waiting function.
|
|
* Removed the PBKDF2 module (use PKCS5).
|
|
* Removed POLARSSL_ERROR_STRERROR_BC (use mbedtls_strerror()).
|
|
* Removed compat-1.2.h (helper for migrating from 1.2 to 1.3).
|
|
* Removed openssl.h (very partial OpenSSL compatibility layer).
|
|
* Configuration options POLARSSL_HAVE_LONGLONG was removed (now always on).
|
|
* Configuration options POLARSSL_HAVE_INT8 and POLARSSL_HAVE_INT16 have
|
|
been removed (compiler is required to support 32-bit operations).
|
|
* Configuration option POLARSSL_HAVE_IPV6 was removed (always enabled).
|
|
* Removed test program o_p_test, the script compat.sh does more.
|
|
* Removed test program ssl_test, superseded by ssl-opt.sh.
|
|
* Removed helper script active-config.pl
|
|
|
|
New deprecations
|
|
* md_init_ctx() is deprecated in favour of md_setup(), that adds a third
|
|
argument (allowing memory savings if HMAC is not used)
|
|
|
|
Semi-API changes (technically public, morally private)
|
|
* Renamed a few headers to include _internal in the name. Those headers are
|
|
not supposed to be included by users.
|
|
* Changed md_info_t into an opaque structure (use md_get_xxx() accessors).
|
|
* Changed pk_info_t into an opaque structure.
|
|
* Changed cipher_base_t into an opaque structure.
|
|
* Removed sig_oid2 and rename sig_oid1 to sig_oid in x509_crt and x509_crl.
|
|
* x509_crt.key_usage changed from unsigned char to unsigned int.
|
|
* Removed r and s from ecdsa_context
|
|
* Removed mode from des_context and des3_context
|
|
|
|
Default behavior changes
|
|
* The default minimum TLS version is now TLS 1.0.
|
|
* RC4 is now blacklisted by default in the SSL/TLS layer, and excluded from the
|
|
default ciphersuite list returned by ssl_list_ciphersuites()
|
|
* Support for receiving SSLv2 ClientHello is now disabled by default at
|
|
compile time.
|
|
* The default authmode for SSL/TLS clients is now REQUIRED.
|
|
* Support for RSA_ALT contexts in the PK layer is now optional. Since is is
|
|
enabled in the default configuration, this is only noticeable if using a
|
|
custom config.h
|
|
* Default DHM parameters server-side upgraded from 1024 to 2048 bits.
|
|
* A minimum RSA key size of 2048 bits is now enforced during ceritificate
|
|
chain verification.
|
|
* Negotiation of truncated HMAC is now disabled by default on server too.
|
|
* The following functions are now case-sensitive:
|
|
mbedtls_cipher_info_from_string()
|
|
mbedtls_ecp_curve_info_from_name()
|
|
mbedtls_md_info_from_string()
|
|
mbedtls_ssl_ciphersuite_from_string()
|
|
mbedtls_version_check_feature()
|
|
|
|
Requirement changes
|
|
* The minimum MSVC version required is now 2010 (better C99 support).
|
|
* The NET layer now unconditionnaly relies on getaddrinfo() and select().
|
|
* Compiler is required to support C99 types such as long long and uint32_t.
|
|
|
|
API changes from the 1.4 preview branch
|
|
* ssl_set_bio_timeout() was removed, split into mbedtls_ssl_set_bio() with
|
|
new prototype, and mbedtls_ssl_set_read_timeout().
|
|
* The following functions now return void:
|
|
mbedtls_ssl_conf_transport()
|
|
mbedtls_ssl_conf_max_version()
|
|
mbedtls_ssl_conf_min_version()
|
|
* DTLS no longer hard-depends on TIMING_C, but uses a callback interface
|
|
instead, see mbedtls_ssl_set_timer_cb(), with the Timing module providing
|
|
an example implementation, see mbedtls_timing_delay_context and
|
|
mbedtls_timing_set/get_delay().
|
|
|
|
Changes
|
|
* mbedtls_ctr_drbg_random() and mbedtls_hmac_drbg_random() are now
|
|
thread-safe if MBEDTLS_THREADING_C is enabled.
|
|
* Reduced ROM fooprint of SHA-256 and added an option to reduce it even
|
|
more (at the expense of performance) MBEDTLS_SHA256_SMALLER.
|
|
|
|
= mbed TLS 1.3 branch
|
|
|
|
Security
|
|
* With authmode set to SSL_VERIFY_OPTIONAL, verification of keyUsage and
|
|
extendedKeyUsage on the leaf certificate was lost (results not accessible
|
|
via ssl_get_verify_results()).
|
|
* Add countermeasure against "Lucky 13 strikes back" cache-based attack,
|
|
https://dl.acm.org/citation.cfm?id=2714625
|
|
|
|
Features
|
|
* Improve ECC performance by using more efficient doubling formulas
|
|
(contributed by Peter Dettman).
|
|

|
|
* Add support for id-at-uniqueIdentifier in X.509 names.
|
|
* Add support for overriding snprintf() (except on Windows) and exit() in
|
|
the platform layer.
|
|
* Add an option to use macros instead of function pointers in the platform
|
|
layer (helps get rid of unwanted references).
|
|
* Improved Makefiles for Windows targets by fixing library targets and making
|
|
cross-compilation easier (thanks to Alon Bar-Lev).
|
|
* The benchmark program also prints heap usage for public-key primitives
|
|
if POLARSSL_MEMORY_BUFFER_ALLOC_C and POLARSSL_MEMORY_DEBUG are defined.
|
|
* New script ecc-heap.sh helps measuring the impact of ECC parameters on
|
|
speed and RAM (heap only for now) usage.
|
|
* New script memory.sh helps measuring the ROM and RAM requirements of two
|
|
reduced configurations (PSK-CCM and NSA suite B).
|
|
* Add config flag POLARSSL_DEPRECATED_WARNING (off by default) to produce
|
|
warnings on use of deprecated functions (with GCC and Clang only).
|
|
* Add config flag POLARSSL_DEPRECATED_REMOVED (off by default) to produce
|
|
errors on use of deprecated functions.
|
|
|
|
Bugfix
|
|
* Fix compile errors with PLATFORM_NO_STD_FUNCTIONS.
|
|
* Fix compile error with PLATFORM_EXIT_ALT (thanks to Rafał Przywara).

entropy_free() to crash (thanks to Rafał Przywara).
|
|
* Fix memory leak when gcm_setkey() and ccm_setkey() are used more than
|
|
once on the same context.

|
* Fix undefined behaviour (memcmp( NULL, NULL, 0 );) in X.509 modules
|
|
(detected by Clang's 3.6 UBSan).
|
|
* mpi_size() and mpi_msb() would segfault when called on an mpi that is
|
|
initialized but not set (found by pravic).
|
|
* Fix detection of support for getrandom() on Linux (reported by syzzer) by
|
|
doing it at runtime (using uname) rather that compile time.
|
|
* Fix handling of symlinks by "make install" (found by Gaël PORTAY).
|
|
* Fix potential NULL pointer dereference (not trigerrable remotely) when
|
|
ssl_write() is called before the handshake is finished (introduced in
|
|
1.3.10) (first reported by Martin Blumenstingl).
|
|
* Fix bug in pk_parse_key() that caused some valid private EC keys to be
|
|
rejected.
|
|
* Fix bug in Via Padlock support (found by Nikos Mavrogiannopoulos).
|
|
* Fix thread safety bug in RSA operations (found by Fredrik Axelsson).
|
|
* Fix hardclock() (only used in the benchmarking program) with some

|
|
in 1.3.10).
|
|
* Add missing extern "C" guard in aesni.h (reported by amir zamani).
|
|
* Add missing dependency on SHA-256 in some x509 programs (reported by
|
|
Gergely Budai).
|
|
* Fix bug related to ssl_set_curves(): the client didn't check that the
|
|
curve picked by the server was actually allowed.
|
|
|
|
Changes
|
|
* Remove bias in mpi_gen_prime (contributed by Pascal Junod).

|
|
* Adjusting/overriding CFLAGS and LDFLAGS with the make build system is now
|
|
more flexible (warning: OFLAGS is not used any more) (see the README)
|
|
(contributed by Alon Bar-Lev).
|
|
* ssl_set_own_cert() no longer calls pk_check_pair() since the
|
|
performance impact was bad for some users (this was introduced in 1.3.10).
|
|
* Move from SHA-1 to SHA-256 in example programs using signatures
|
|
(suggested by Thorsten Mühlfelder).
|
|
* Remove some unneeded inclusions of header files from the standard library
|
|
"minimize" others (eg use stddef.h if only size_t is needed).
|
|
* Change #include lines in test files to use double quotes instead of angle
|
|
brackets for uniformity with the rest of the code.
|
|
* Remove dependency on sscanf() in X.509 parsing modules.

|
Security
|
|
* NULL pointer dereference in the buffer-based allocator when the buffer is
|
|
full and polarssl_free() is called (found by Mark Hasemeyer)
|
|
(only possible if POLARSSL_MEMORY_BUFFER_ALLOC_C is enabled, which it is
|
|
not by default).
|
|
* Fix remotely-triggerable uninitialised pointer dereference caused by
|
|
crafted X.509 certificate (TLS server is not affected if it doesn't ask for a
|
|
client certificate) (found using Codenomicon Defensics).
|
|
* Fix remotely-triggerable memory leak caused by crafted X.509 certificates
|
|
(TLS server is not affected if it doesn't ask for a client certificate)
|
|
(found using Codenomicon Defensics).
|
|
* Fix potential stack overflow while parsing crafted X.509 certificates
|
|
(TLS server is not affected if it doesn't ask for a client certificate)
|
|
(found using Codenomicon Defensics).
|
|
* Fix timing difference that could theoretically lead to a
|
|
Bleichenbacher-style attack in the RSA and RSA-PSK key exchanges
|
|
(reported by Sebastian Schinzel).
|
|
|
|
Features

|
* Add support for FALLBACK_SCSV (draft-ietf-tls-downgrade-scsv).
|
|
* Add support for Extended Master Secret (draft-ietf-tls-session-hash).
|
|
* Add support for Encrypt-then-MAC (RFC 7366).
|
|
* Add function pk_check_pair() to test if public and private keys match.
|
|
* Add x509_crl_parse_der().
|
|
* Add compile-time option POLARSSL_X509_MAX_INTERMEDIATE_CA to limit the
|
|
length of an X.509 verification chain.
|
|
* Support for renegotiation can now be disabled at compile-time
|
|
* Support for 1/n-1 record splitting, a countermeasure against BEAST.
|
|
* Certificate selection based on signature hash, preferring SHA-1 over SHA-2
|
|
for pre-1.2 clients when multiple certificates are available.
|
|
* Add support for getrandom() syscall on recent Linux kernels with Glibc or
|
|
a compatible enough libc (eg uClibc).
|

|
|
while using the default ciphersuite list.
|
|
* Added new error codes and debug messages about selection of
|
|
ciphersuite/certificate.
|
|
|
|
Bugfix
|
|
* Stack buffer overflow if ctr_drbg_update() is called with too large
|
|
add_len (found by Jean-Philippe Aumasson) (not triggerable remotely).
|
|
* Possible buffer overflow of length at most POLARSSL_MEMORY_ALIGN_MULTIPLE
|
|
if memory_buffer_alloc_init() was called with buf not aligned and len not
|
|
a multiple of POLARSSL_MEMORY_ALIGN_MULTIPLE (not triggerable remotely).
|
|
* User set CFLAGS were ignored by Cmake with gcc (introduced in 1.3.9, found
|
|
by Julian Ospald).
|
|
* Fix potential undefined behaviour in Camellia.

|
* Fix unchecked return code in x509_crt_parse_path() on Windows (found by
|
|
Peter Vaskovic).
|
|
* Fix assembly selection for MIPS64 (thanks to James Cowgill).
|
|
* ssl_get_verify_result() now works even if the handshake was aborted due
|
|
to a failed verification (found by Fredrik Axelsson).
|
|
* Skip writing and parsing signature_algorithm extension if none of the
|
|
key exchanges enabled needs certificates. This fixes a possible interop
|
|
issue with some servers when a zero-length extension was sent. (Reported
|
|
by Peter Dettman.)
|
|
* On a 0-length input, base64_encode() did not correctly set output length
|
|
(found by Hendrik van den Boogaard).
|
|
|
|
Changes
|
|
* Use deterministic nonces for AEAD ciphers in TLS by default (possible to
|
|
switch back to random with POLARSSL_SSL_AEAD_RANDOM_IV in config.h).
|
|
* Blind RSA private operations even when POLARSSL_RSA_NO_CRT is defined.
|
|
* ssl_set_own_cert() now returns an error on key-certificate mismatch.
|
|
* Forbid repeated extensions in X.509 certificates.
|
|
* debug_print_buf() now prints a text view in addition to hexadecimal.
|
|
* A specific error is now returned when there are ciphersuites in common
|
|
but none of them is usable due to external factors such as no certificate
|
|
with a suitable (extended)KeyUsage or curve or no PSK set.
|
|
* It is now possible to disable negotiation of truncated HMAC server-side
|
|
at runtime with ssl_set_truncated_hmac().
|
|
* Example programs for SSL client and server now disable SSLv3 by default.
|
|
* Example programs for SSL client and server now disable RC4 by default.
|
|
* Use platform.h in all test suites and programs.

Security
|
|
* Lowest common hash was selected from signature_algorithms extension in
|
|
TLS 1.2 (found by Darren Bane) (introduced in 1.3.8).
|
|
* Remotely-triggerable memory leak when parsing some X.509 certificates
|
|
(server is not affected if it doesn't ask for a client certificate)
|
|
(found using Codenomicon Defensics).
|
|
* Remotely-triggerable memory leak when parsing crafted ClientHello
|
|
(not affected if ECC support was compiled out) (found using Codenomicon

|
|
are defined but not POLARSSL_HAVE_TIME (found by Stephane Di Vito).
|
|
* Remove non-existent file from VS projects (found by Peter Vaskovic).
|
|
* ssl_read() could return non-application data records on server while
|
|
renegotation was pending, and on client when a HelloRequest was received.
|
|
* Server-initiated renegotiation would fail with non-blocking I/O if the
|
|
write callback returned WANT_WRITE when requesting renegotiation.
|
|
* ssl_close_notify() could send more than one message in some circumstances
|
|
with non-blocking I/O.
|
|
* Fix compiler warnings on iOS (found by Sander Niemeijer).
|
|
* x509_crt_parse() did not increase total_failed on PEM error

|
|
RSA is disabled, larger if POLARSSL_MPI_MAX_SIZE is larger.

* Added ssl_set_max_version() to allow clients to offer a lower maximum
|
|
supported version to a server to help buggy server implementations.
|
|
(Closes ticket #36)
|
|
* Added cipher_get_cipher_mode() and cipher_get_cipher_operation()
|
|
introspection functions (Closes ticket #40)
|
|
* Added CTR_DRBG based on AES-256-CTR (NIST SP 800-90) random generator
|
|
* Added a generic entropy accumulator that provides support for adding
|
|
custom entropy sources and added some generic and platform dependent
|
|
entropy sources
|
|
|
|
Changes
|
|
* Documentation for AES and Camellia in modes CTR and CFB128 clarified.
|
|
* Fixed rsa_encrypt and rsa_decrypt examples to use public key for
|
|
encryption and private key for decryption. (Closes ticket #34)
|
|
* Inceased maximum size of ASN1 length reads to 32-bits.
|
|
* Added an EXPLICIT tag number parameter to x509_get_ext()
|
|
* Added a separate CRL entry extension parsing function
|
|
* Separated the ASN.1 parsing code from the X.509 specific parsing code.
|
|
So now there is a module that is controlled with POLARSSL_ASN1_PARSE_C.
|
|
* Changed the defined key-length of DES ciphers in cipher.h to include the
|
|
parity bits, to prevent mistakes in copying data. (Closes ticket #33)
|
|

|
|
(Credits go to Marco Lizza)
|
|
* Added POLARSSL_MPI_WINDOW_SIZE definition to allow easier time to memory

|
* Introduced POLARSSL_MPI_MAX_SIZE and POLARSSL_MPI_MAX_BITS for MPI size
|
|
management (Closes ticket #44)
|
|
* Changed the used random function pointer to more flexible format. Renamed
|
|
havege_rand() to havege_random() to prevent mistakes. Lots of changes as
|
|
a consequence in library code and programs
|
|
* Moved all examples programs to use the new entropy and CTR_DRBG
|
|
* Added permissive certificate parsing to x509parse_crt() and
|
|
x509parse_crtfile(). With permissive parsing the parsing does not stop on
|
|
encountering a parse-error. Beware that the meaning of return values has
|
|
changed!
|
|
* All error codes are now negative. Even on mermory failures and IO errors.
|
|
|
|
Bugfix
|
|
* Fixed faulty HMAC-MD2 implementation. Found by dibac. (Closes
|
|
ticket #37)
|
|
* Fixed a bug where the CRL parser expected an EXPLICIT ASN.1 tag
|
|
before version numbers
|
|
* Allowed X509 key usage parsing to accept 4 byte values instead of the
|
|
standard 1 byte version sometimes used by Microsoft. (Closes ticket #38)
|
|
* Fixed incorrect behaviour in case of RSASSA-PSS with a salt length
|
|
smaller than the hash length. (Closes ticket #41)
|
|
* If certificate serial is longer than 32 octets, serial number is now
|
|
appended with '....' after first 28 octets
|
|
* Improved build support for s390x and sparc64 in bignum.h
|
|
* Fixed MS Visual C++ name clash with int64 in sha4.h
|
|
* Corrected removal of leading "00:" in printing serial numbers in
|
|
certificates and CRLs

= Version 1.0.0 released on 2011-07-27
|
|
Features
|
|
* Expanded cipher layer with support for CFB128 and CTR mode
|
|
* Added rsa_encrypt and rsa_decrypt simple example programs.
|
|
|
|
Changes

|
|
codes instead of integers
|
|
|
|
Bugfix
|
|
* Undid faulty bug fix in ssl_write() when flushing old data (Ticket
|
|
#18)
|
|
|
|
= Version 0.99-pre5 released on 2011-05-26
|
|
Features
|
|
* Added additional Cipher Block Modes to symmetric ciphers
|
|
(AES CTR, Camellia CTR, XTEA CBC) including the option to
|
|
enable and disable individual modes when needed
|
|
* Functions requiring File System functions can now be disabled
|
|
by undefining POLARSSL_FS_IO
|
|
* A error_strerror function() has been added to translate between
|
|
error codes and their description.

|
* Added mpi_get_bit() and mpi_set_bit() individual bit setter/getter
|
|
functions.
|
|
* Added ssl_mail_client and ssl_fork_server as example programs.
|
|
|
|
Changes
|
|
* Major argument / variable rewrite. Introduced use of size_t
|
|
instead of int for buffer lengths and loop variables for
|
|
better unsigned / signed use. Renamed internal bigint types
|
|
t_int and t_dbl to t_uint and t_udbl in the process
|
|
* mpi_init() and mpi_free() now only accept a single MPI
|
|
argument and do not accept variable argument lists anymore.
|
|
* The error codes have been remapped and combining error codes
|
|
is now done with a PLUS instead of an OR as error codes
|
|
used are negative.
|
|
* Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
|
|
net_recv() now returns 0 on EOF instead of
|
|
POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
|
|
POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
|
|
ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
|
|
after the handshake.
|
|
* Network functions now return POLARSSL_ERR_NET_WANT_READ or
|
|
POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous
|
|
POLARSSL_ERR_NET_TRY_AGAIN
|
|
|

|
functionality as well.
|
|
* Added mpi_fill_random() for centralized filling of big numbers
|
|
with random data (Fixed ticket #10)
|
|
|
|
Changes
|
|
* Debug print of MPI now removes leading zero octets and
|
|
displays actual bit size of the value.
|
|
* x509parse_key() (and as a consequence x509parse_keyfile())
|
|
does not zeroize memory in advance anymore. Use rsa_init()
|
|
before parsing a key or keyfile!
|
|
|
|
Bugfix
|
|

|
|
