AlgorithmParameterSpec
public class MGF1ParameterSpec extends Object implements AlgorithmParameterSpec
Its ASN.1 definition in PKCS#1 standard is described below:
PKCS1MGFAlgorithms ALGORITHM-IDENTIFIER ::= { { OID id-mgf1 PARAMETERS HashAlgorithm }, ... -- Allows for future expansion -- }where
HashAlgorithm ::= AlgorithmIdentifier { {OAEP-PSSDigestAlgorithms} } 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 -- }
