Function description
Initializes the CRYP peripheral in DES CBC encryption mode
using DMA.
Parameters
hcryp: pointer to a CRYP_HandleTypeDef structure that
contains the configuration information for CRYP module
pPlainData: Pointer to the plaintext buffer
Size: Length of the plaintext buffer, must be a multiple of 8
pCypherData: Pointer to the cyphertext buffer
Return values
HAL: status
