newCipher

public static Cipher newCipher(int operationMode,
                               SecretKey key,
                               AlgorithmParameterSpec paramSpec,
                               String algorithm)
                        throws NoSuchAlgorithmException,
                               NoSuchPaddingException,
                               InvalidKeyException,
                               InvalidAlgorithmParameterException

Factory method for creating a new Cipher from the given parameters.

Parameters:

operationMode - the operation mode

key - the key

paramSpec - the param spec

algorithm - the algorithm

Returns:

the cipher

Throws:

NoSuchAlgorithmException - is thrown if instantiation of the SecretKeyFactory object fails.

NoSuchPaddingException - is thrown if instantiation of the cypher object fails.

InvalidKeyException - is thrown if initialization of the cypher object fails.

InvalidAlgorithmParameterException - is thrown if initialization of the cypher object fails.

newCipher

public static Cipher newCipher(String algorithm)
                        throws NoSuchAlgorithmException,
                               NoSuchPaddingException

Factory method for creating a new Cipher from the given algorithm.

Parameters:

algorithm - the alg

Returns:

the cipher

Throws:

NoSuchAlgorithmException - is thrown if instantiation of the SecretKeyFactory object fails.

NoSuchPaddingException - is thrown if instantiation of the cypher object fails.

newCipher

public static Cipher newCipher(String algorithm,
                               String provider)
                        throws NoSuchAlgorithmException,
                               NoSuchProviderException,
                               NoSuchPaddingException

Factory method for creating a new Cipher from the given algorithm and provider.

Parameters:

algorithm - the algorithm

provider - the provider

Returns:

the cipher

Throws:

NoSuchAlgorithmException - is thrown if instantiation of the SecretKeyFactory object fails.

NoSuchProviderException - is thrown if the specified provider is not registered in the security provider list.

NoSuchPaddingException - is thrown if algorithm contains a padding scheme that is not available.
