1 This test exercises using a different hash function parameter to the mask gen
2 function (SHA-256 for the hash, but SHA-512 for the MGF1 hash).
4 This test data was constructed manually by calling signing functions from
7 It constructs an RSASSA-PSS signature using:
8 * Key with modulus 1024 bit
10 * Digest function of SHA-256
11 * Mask gen function of MGF1 with SHA-512
