/** List of encryption (cipher) algorithms provided in this package.
*
*
* Contains a list of provider names and their implementation classes, * in the form of: *
* { "Cipher.alg", "pkg.class" }
* where alg specifies the "standard" name of the encryption
* algorithm, and pkg.class is the actual implementation package and
* class name.
*
* * The alg name can be a single algorithm name (e.g., "DES"); * or it can be composed of two parts "alg/mode", * specifying an algorithm and a block mode (e.g., "DES/CBC"); * or it can be composed of three parts * "alg/mode/pad", specifying an additional * padding type (e.g., "DES/CBC/PKCS5Padding"), and the mode * part can be left unspecified (e.g., "DES//PKCS5Padding"). * *
* Valid mode settings are: *
* ECB, CBC, CFB, OFB, PCBC
*
* * Valid pad settings are: *
* PKCS5Padding
