CDES_EDE2

CDES_EDE2 class does not have a base class.

CDES_EDE2 class assists you in performing DES-EDE2 encryption/decryption.

To encrypt/decrypt one or more continuous memory block(s) of fixed CDES_EDE2::BLOCKSIZE  size, perform the following:

• Instantiate a CDES_EDE2 object passing to the constructor the secret key and the cipher direction (SLC_ENCRYPT or SLC_DECRYPT).

• Call the ProcessBlock member function for each memory block to perform encryption/decryption.

• Call the Init member function to initialize the CDES_EDE2 object with another secret key and/or to change its cipher direction.

Note. The above algorithm corresponds to ECB mode of operation. QuickCrypt Library supports also CBC, CFB, OFB and Counter modes of operation.
