DESX API Overview

DESX API assists you in performing DESX encryption/decryption.

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

• Allocate at least SLC_DESX_CONTEXTSIZE bytes for the context.

• Call the SL_DESX_Init function to initialize the context with the secret key and the cipher direction (SLC_ENCRYPT or SLC_DECRYPT).

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

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