PSSParameterSpecpublic class PSSParameterSpec extends Object implements AlgorithmParameterSpec| The parameter specification for the RSA-PSS Signature scheme.
Defined in the PKCS #1 v2.1
standard.
|
| Fields Summary |
|---|
| public static final PSSParameterSpec | DEFAULTThe default parameter specification. It specifies the following parameters:
- message digest: {@code "SHA-1"}
- mask generation function (mgf): {@code "MGF1"}
- parameters for the mgf: {@link MGF1ParameterSpec#SHA1}
- salt length: {@code 20}
- trailer field: {@code -1}

public PSSParameterSpec(int saltLen)Creates a new {@code PSSParameterSpec} with the specified salt length
and the default values.

| public PSSParameterSpec(String mdName, String mgfName, AlgorithmParameterSpec mgfSpec, int saltLen, int trailerField)Creates a new {@code PSSParameterSpec} with the specified message digest
name, mask generation function name, mask generation function parameters,
salt length, and trailer field value.
