Remarks
This class specifies the set of parameters used with OAEP Padding, as defined in the PKCS #1 standard.
Its ASN.1 definition in PKCS#1 standard is described below:
RSAES-OAEP-params ::= SEQUENCE {
hashAlgorithm [0] OAEP-PSSDigestAlgorithms DEFAULT sha1,
maskGenAlgorithm [1] PKCS1MGFAlgorithms DEFAULT mgf1SHA1,
pSourceAlgorithm [2] PKCS1PSourceAlgorithms DEFAULT pSpecifiedEmpty
}
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 --
}
PKCS1MGFAlgorithms ALGORITHM-IDENTIFIER ::= {
{ OID id-mgf1 PARAMETERS OAEP-PSSDigestAlgorithms },
... -- Allows for future expansion --
}
PKCS1PSourceAlgorithms ALGORITHM-IDENTIFIER ::= {
{ OID id-pSpecified PARAMETERS OCTET STRING },
... -- Allows for future expansion --
}
Note: the OAEPParameterSpec.DEFAULT uses the following: message digest -- "SHA-1" mask generation function (mgf) -- "MGF1" parameters for mgf -- MGF1ParameterSpec.SHA1 source of encoding input -- PSource.PSpecified.DEFAULT
