getInstance

public static Cipher getInstance(java.lang.String alg,
                                 java.lang.String pad,
                                 java.lang.String mode)

                                 javax.crypto.NoSuchPaddingException

Create an instance of a cipher algorithm.

Parameters:

alg - Cryptographic cipher algorithm name (e.g., "AES", "IDEA", etc.).

pad - Padding scheme (e.g., "NoPadding", "PKCS5Padding", etc.); if this is empty ("") or null, a default scheme is used. See the PADDING_XXX constants.

mode - Cryptographic operating mode (e.g., "ECB", "CBC", "CFB", etc.); if this is empty ("") or null, a default mode is used. See the MODE_XXX constants.

Returns:

A cipher object of the specified type. +REDO

Throws:
