Constructor Details

GnuDSAPrivateKey

public GnuDSAPrivateKey(BigInteger x,
                        BigInteger p,
                        BigInteger q,
                        BigInteger g)

Method Details

getAlgorithm

public String getAlgorithm()
Specified by:
getAlgorithm in interface Key

getEncoded

public byte[] getEncoded()
Encodes this key as a PrivateKeyInfo, as described in PKCS #8. The ASN.1 specification for this structure is:
 PrivateKeyInfo ::= SEQUENCE {
   version Version,
   privateKeyAlgorithm PrivateKeyAlgorithmIdentifier,
   privateKey PrivateKey,
   attributes [0] IMPLICIT Attributes OPTIONAL }

 Version ::= INTEGER

 PrivateKeyAlgorithmIdentifier ::= AlgorithmIdentifier

 PrivateKey ::= OCTET STRING

 Attributes ::= SET OF Attribute
 

DSA private keys (in Classpath at least) have no attributes.

Specified by:
getEncoded in interface Key

getFormat

public String getFormat()
Specified by:
getFormat in interface Key

getParams

public DSAParams getParams()
Specified by:
getParams in interface DSAKey

getX

public BigInteger getX()
Specified by:
getX in interface DSAPrivateKey

toString

public String toString()
Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() and such.

It is typical, but not required, to ensure that this method never completes abruptly with a RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

Overrides:
toString in interface Object
Returns:
the String representing this Object, which may be null
