class MGF1ParameterSpec
- All Implemented Interfaces:
- AlgorithmParameterSpec
public class MGF1ParameterSpec
extends Object
implements AlgorithmParameterSpec
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-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 --
}
Constructor Summary |
Constructs a parameter set for mask generation function MGF1
as defined in the PKCS #1 standard.
|
Method Summary |
String |
Returns the algorithm name of the message digest used by the mask
generation function.
