From 65593d2ddd6cd6eb59207a56c373f4dde968f16a Mon Sep 17 00:00:00 2001 From: Jaeden Amero Date: Tue, 11 Sep 2018 14:05:42 +0100 Subject: [PATCH] rsa: pss: Add no possible salt size tests Add signing tests with 528-bit and 520-bit RSA keys with SHA-512. These selections of key and hash size should lead to an error returned, as there is not enough room for our chosen minimum salt size of two bytes less than the hash size. These test the boundary around an available salt length of 0 or -1 bytes. The RSA keys were generated with OpenSSL 1.1.1-pre8. $ openssl genrsa 520 Generating RSA private key, 520 bit long modulus (2 primes) .............++++++++++++ .................++++++++++++ e is 65537
