Method Detail

getAlgorithmback to summary
public String getAlgorithm()

Implements java.security.Key.getAlgorithm.

Doc from java.security.Key.getAlgorithm.

Returns the standard algorithm name for this key. For example, "DSA" would indicate that this key is a DSA key. See the key related sections (KeyFactory, KeyGenerator, KeyPairGenerator, and SecretKeyFactory) in the Java Security Standard Algorithm Names Specification for information about standard key algorithm names.

Returns:String

the name of the algorithm associated with this key.

getEncodedback to summary
public byte[] getEncoded()

Implements java.security.Key.getEncoded.

Doc from java.security.Key.getEncoded.

Returns the key in its primary encoding format, or null if this key does not support encoding.

Returns:byte[]

the encoded key, or null if the key does not support encoding.

getFormatback to summary
public String getFormat()

Implements java.security.Key.getFormat.

Doc from java.security.Key.getFormat.

Returns the name of the primary encoding format of this key, or null if this key does not support encoding. The primary encoding format is named in terms of the appropriate ASN.1 data format, if an ASN.1 specification for this key exists. For example, the name of the ASN.1 data format for public keys is SubjectPublicKeyInfo, as defined by the X.509 standard; in this case, the returned format is "X.509". Similarly, the name of the ASN.1 data format for private keys is PrivateKeyInfo, as defined by the PKCS #8 standard; in this case, the returned format is "PKCS#8".

Returns:String

the primary encoding format of the key.

getParamsback to summary
public DHParameterSpec getParams()

Overrides default javax.crypto.interfaces.DHPublicKey.getParams.

Doc from javax.crypto.interfaces.DHPublicKey.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.

Returns:DHParameterSpec

the associated parameters, may be null

getYback to summary
public BigInteger getY()

Implements javax.crypto.interfaces.DHPublicKey.getY.

Doc from javax.crypto.interfaces.DHPublicKey.getY.

Returns the public value, y.

Returns:BigInteger

the public value, y
