Examples of MGF1ParameterSpec

java.security.spec.MGF1ParameterSpec

etf.org/rfc/rfc3447.txt">PKCS #1 v2.1 standard.

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

 MGF1Parameters ::= OAEP-PSSDigestAlgorthms

where

 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 -- }
