C++ (Cpp) bcal_cbc_loadIV Examples

Example #1

File: bcal-cbc.c Project: Sergoi/avr-crypto-lib

void bcal_cbc_encMsg(const void *iv, void *msg, uint16_t msg_blocks, bcal_cbc_ctx_t *ctx){
	bcal_cbc_loadIV(iv, ctx);
	while(msg_blocks--){
		bcal_cbc_encNext(msg, ctx);
		msg = (uint8_t*)msg + ctx->blocksize_B;
	}
}

Example #2

File: AESLib.c Project: 9zigen/AESLib

// prepare an encrypted to use for encrypting multiple blocks lateron.
// key and iv are assumed to be both 192bit thus 24 uint8_t's
aes_context aes192_cbc_enc_start(const uint8_t* key, const void* iv){
	bcal_cbc_ctx_t* ctx = (bcal_cbc_ctx_t*)malloc(sizeof(bcal_cbc_ctx_t));
	uint8_t r = bcal_cbc_init(&aes192_desc, key, 192, ctx);
	if (r) {
		free(ctx);
		return NULL;
	}
	bcal_cbc_loadIV(iv, ctx);
	return (aes_context)ctx;
