Constructor Detail

CipherSuite

public CipherSuite(javax.crypto.Cipher encrypt,
                   javax.crypto.Cipher decrypt,
                   java.lang.String cipherPrefix,
                   boolean urlSafe)

Constructor.

Parameters:

encrypt - An encrypt cipher

decrypt - An decrypt cipher

cipherPrefix - A cipher prefix (E.g. {DES})

urlSafe - if true this encoder will emit - and _ instead of the usual + and / characters. Note: no padding is added when encoding using the URL-safe alphabet.
