	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).

	3

	4 This test data was constructed manually by calling signing functions from

	5 OpenSSL code.

	6

	7 It constructs an RSASSA-PSS signature using:

	8 * Key with modulus 1024 bit

	9 * Salt length 33 bytes

	10 * Digest function of SHA-256

	11 * Mask gen function of MGF1 with SHA-512
