| This test exercises using a different hash function parameter to the mask gen |
| function (SHA-256 for the hash, but SHA-512 for the MGF1 hash). |
| |
| This test data was constructed manually by calling signing functions from |
| OpenSSL code. |
| |
| It constructs an RSASSA-PSS signature using: |
| * Key with modulus 1024 bit |
| * Salt length 33 bytes |
| * Digest function of SHA-256 |
| * Mask gen function of MGF1 with SHA-512 |
