1 The key, message, and signature come from:
2 http://csrc.nist.gov/groups/STM/cavp/documents/dss/186-2rsatestvectors.zip (SigVerPSS_186-3.rsp)
4 (The algorithm DER was synthesized to match, and the signature wrapped in a BIT STRING).
6 It uses an RSA key with modulus length of 1024 bits, PSS padding,
7 SHA-256 as the digest, MGF1 with SHA-256, and salt length of 10.
