The interface to a public or private key in
PKCS#1 v2.2 standard,
such as those for RSA, or RSASSA-PSS algorithms.
Summary
Public methods
getModulus
public abstract BigInteger getModulus ()
Returns the modulus.
getParams
public AlgorithmParameterSpec getParams ()
Returns the parameters associated with this key.
The parameters are optional and may be either
explicitly specified or implicitly created during
key pair generation.
Implementation Requirements:
- The default implementation returns
null.
