 Encrypt using CBC.
int(* cfb128_func )(void *ctx, operation_t mode, size_t length, size_t *iv_off, unsigned char *iv, const unsigned char *input, unsigned char *output)
 Encrypt using CFB128.
int(* ctr_func )(void *ctx, size_t length, size_t *nc_off, unsigned char *nonce_counter, unsigned char *stream_block, const unsigned char *input, unsigned char *output)
 Encrypt using CTR.
int(* setkey_enc_func )(void *ctx, const unsigned char *key, unsigned int key_length)
 Set key for encryption purposes.
int(* setkey_dec_func )(void *ctx, const unsigned char *key, unsigned int key_length)
 Set key for decryption purposes.
void *(* ctx_alloc_func )(void)
 Allocate a new context.
void(* ctx_free_func )(void *ctx)
 Free the given context.
