                                java.security.Key key,
                                java.security.spec.AlgorithmParameterSpec params,

Translation method between PBEParameterSpec and PBEParameterSpec: initialize this cipher with a key, a set of algorithm parameters, and a source of randomness. The cipher is initialized for one of the following four operations: encryption, decryption, key wrapping or key unwrapping, depending on the value of opMode. If this cipher (including its underlying feedback or padding scheme) requires any random bytes (e.g., for parameter generation), it will get them from random. Note that when a Cipher object is initialized, it loses all previously-acquired state. In other words, initializing a Cipher is equivalent to creating a new instance of that Cipher and initializing it.

Overrides:

engineInit in class Cipher

Parameters:

opMode - the operation mode of this cipher (this is one of the following: ENCRYPT_MODE, DECRYPT_MODE)

key - the encryption key

params - the algorithm parameters

javaRand - the source of randomness

Throws:

java.security.InvalidKeyException - if the given key is inappropriate for initializing this cipher

java.security.InvalidAlgorithmParameterException - if the given algorithm parameters are inappropriate for this cipher, or if this cipher is being initialized for decryption and requires algorithm parameters and the parameters are null.
