SecretKey

• java.lang.Object

Fields Summary
String	alg Type of key, e.g. DES, RSA etc.
byte[]	secret Local secret.

Constructors Summary

public SecretKey(byte[] key, int offset, int len, String algorithm) Constructs a secret key from the given byte array, using the first len bytes of key, starting at offset inclusive. The bytes that constitute the secret key are those between key[offset] and key[offset+len-1] inclusive. This constructor does not check if the given bytes indeed specify a secret key of the specified algorithm. For example, if the algorithm is DES, this constructor does not check if key is 8 bytes long, and also does not check for weak or semi-weak keys. In order for those checks to be performed, an algorithm-specific key specification class must be used. param key the key material of the secret key. param offset the offset in key where the key material starts. param len the length of the key material. param algorithm the ID of the secret-key algorithm to be associated with the given key material. alg = algorithm; secret = Util.cloneSubarray(key, offset, len);

Methods Summary
public java.lang.String	getAlgorithm() Returns the name of the algorithm associated with this secret key. return the secret key algorithm. return alg;
public byte[]	getEncoded() Returns the key material of this secret key. return the key material return Util.cloneArray(secret);
public java.lang.String	getFormat() Returns the name of the encoding format for this secret key. return the string "RAW". return "RAW";
