Remarks

This class specifies a parameter spec for RSA-PSS signature scheme, as defined in the PKCS#1 v2.1 standard.

Its ASN.1 definition in PKCS#1 standard is described below:

RSASSA-PSS-params ::= SEQUENCE {
              hashAlgorithm      [0] OAEP-PSSDigestAlgorithms  DEFAULT sha1,
              maskGenAlgorithm   [1] PKCS1MGFAlgorithms  DEFAULT mgf1SHA1,
              saltLength         [2] INTEGER  DEFAULT 20,
              trailerField       [3] INTEGER  DEFAULT 1
            }

where

OAEP-PSSDigestAlgorithms    ALGORITHM-IDENTIFIER ::= {
              { OID id-sha1 PARAMETERS NULL   }|
              { OID id-sha224 PARAMETERS NULL   }|
              { OID id-sha256 PARAMETERS NULL }|
              { OID id-sha384 PARAMETERS NULL }|
              { OID id-sha512 PARAMETERS NULL },
              ...  -- Allows for future expansion --
            }

            PKCS1MGFAlgorithms    ALGORITHM-IDENTIFIER ::= {
              { OID id-mgf1 PARAMETERS OAEP-PSSDigestAlgorithms },
              ...  -- Allows for future expansion --
            }

Note: the PSSParameterSpec.DEFAULT uses the following: message digest -- "SHA-1" mask generation function (mgf) -- "MGF1" parameters for mgf -- MGF1ParameterSpec.SHA1 SaltLength -- 20 TrailerField -- 1
