This class specifies the set of parameters used with mask generation function MGF1 in OAEP Padding and RSA-PSS signature scheme, as defined in the PKCS #1 v2.1 standard.
Its ASN.1 definition in PKCS#1 standard is described below:
MGF1Parameters ::= OAEP-PSSDigestAlgorthmswhere
OAEP-PSSDigestAlgorithms ALGORITHM-IDENTIFIER ::= { { OID id-sha1 PARAMETERS NULL }| { OID id-sha256 PARAMETERS NULL }| { OID id-sha384 PARAMETERS NULL }| { OID id-sha512 PARAMETERS NULL }, ... -- Allows for future expansion -- }
