                     ##### How to use this driver #####
  ==============================================================================
    [..]
    The CRYP extension HAL driver can be used as follows:
    (#)After AES-GCM or AES-CCM  Encryption/Decryption user can start following API
       to get the  authentication messages :
      (##) HAL_CRYPEx_AESGCM_GenerateAuthTAG
      (##) HAL_CRYPEx_AESCCM_GenerateAuthTAG
