Object
dw.crypto.WeakCipher
This API provides access to Deprecated algorithms.

See Cipher for full documentation. WeakCipher is simply a drop-in replacement that only supports deprecated algorithms and key lengths. This is helpful when you need to deal with weak algorithms for backward compatibility purposes, but Cipher should always be used for new development and for anything intended to be secure.

Note: this class handles sensitive security-related data. Pay special attention to PCI DSS v3 requirements 2, 4, and 12.

Constants
CHAR_ENCODING  :  String = "UTF8"
Strings containing keys, plain texts, cipher texts etc. are internally converted into byte arrays using this encoding (currently UTF8).
