javax.crypto.spec

Class SecretKeySpec

public class SecretKeySpec extends Object implements KeySpec, SecretKey

This is a simple wrapper around a raw byte array, for ciphers that do not require any key parameters other than the bytes themselves.

Since this class implements {@link javax.crypto.SecretKey}, which in turn extends {@link java.security.Key}, so instances of this class may be passed directly to the init() methods of {@link javax.crypto.Cipher}.

Constructor Summary
	SecretKeySpec(byte[] key, String algorithm) Create a new secret key spec from an entire byte array.
	SecretKeySpec(byte[] key, int off, int len, String algorithm) Create a new secret key spec from part of a byte array.

Method Summary
boolean	equals(Object o)
String	getAlgorithm() Return the name of the algorithm associated with this secret key.
byte[]	getEncoded() Return the key as a byte array.
String	getFormat() This key's format, which is always "RAW".
