Remarks

This class specifies a parameter spec for RSASSA-PSS signature scheme, as defined in the PKCS#1 v2.2 standard.

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

RSASSA-PSS-params ::= SEQUENCE {
              hashAlgorithm      [0] HashAlgorithm      DEFAULT sha1,
              maskGenAlgorithm   [1] MaskGenAlgorithm   DEFAULT mgf1SHA1,
              saltLength         [2] INTEGER            DEFAULT 20,
              trailerField       [3] TrailerField       DEFAULT trailerFieldBC(1)
            }

where

HashAlgorithm ::= AlgorithmIdentifier {
              {OAEP-PSSDigestAlgorithms}
            }
            MaskGenAlgorithm ::= AlgorithmIdentifier { {PKCS1MGFAlgorithms} }
            TrailerField ::= INTEGER { trailerFieldBC(1) }

            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 }|
              { OID id-sha512-224 PARAMETERS NULL }|
              { OID id-sha512-256 PARAMETERS NULL },
              ...  -- Allows for future expansion --
            }
            PKCS1MGFAlgorithms    ALGORITHM-IDENTIFIER ::= {
              { OID id-mgf1 PARAMETERS HashAlgorithm },
              ...  -- 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
