PACESecretKeySpec

public PACESecretKeySpec(byte[] key,
                         int offset,
                         int len,
                         String algorithm,
                         byte paceKeyReference)

Constructs a secret key from the given byte array, using the first len bytes of key, starting at offset inclusive.

Parameters:

key - the key bytes

offset - the offset with key

len - the length of the key within key

algorithm - the name of the secret-key algorithm to be associated with the given key material

paceKeyReference - a reference specifying the type of key from BSI TR-03110 (Appendix B)
