com.tencent.kona.sun.security.rsa.PSSParameters

public final class PSSParameters
extends java.security.AlgorithmParametersSpi

This class implements the PSS parameters used with the RSA signatures in PSS padding. Here is its ASN.1 definition: RSASSA-PSS-params ::= SEQUENCE { hashAlgorithm [0] HashAlgorithm DEFAULT sha1, maskGenAlgorithm [1] MaskGenAlgorithm DEFAULT mgf1SHA1, saltLength [2] INTEGER DEFAULT 20 trailerField [3] TrailerField DEFAULT trailerFieldBC }
