RSA-SSA Scheme Functions
This subsection describes functions implementing RSASSA-PSS_5 signature scheme with appendix PKCS 1.2.1.
To invoke RSASign_PSS or RSAVerify_PSS primitive, supply the IppsRSAPrivateKeyState and/or IppsRSAPublicKeyState context initialized by a suitable function (see RSA_InitPublicKey, RSA_InitPrivateKeyType1, or RSA_InitPrivateKeyType2 for details).
