org.mozilla.jss.provider.java.security.RSAPSSAlgorithmParameters

public class RSAPSSAlgorithmParameters
extends java.security.AlgorithmParametersSpi

A RSAPSSAlgorithmParameter implements the trandcoding between a PSSAlgorithmSpec instance and the DER-encoded form. 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 -- }
