C++ (Cpp) datablob_alloc Examples

Example #1

File: crypto_openssl.c Project: DrTusk/FreeRDP

int
crypto_cert_get_public_key(CryptoCert cert, DATABLOB * public_key)
{
	int length;
	int success = 1;
	EVP_PKEY *pkey = NULL;
	unsigned char *p;

	pkey = X509_get_pubkey(cert->px509);
	if (!pkey)
	{
		printf("crypto_cert_get_public_key: X509_get_pubkey() failed\n");
		success = 0;
		goto exit;
	}

	length = i2d_PublicKey(pkey, NULL);

	if (length < 1)
	{
		printf("crypto_cert_get_public_key: i2d_PublicKey() failed\n");
		success = 0;
		goto exit;
	}

	datablob_alloc(public_key, length);
	p = (unsigned char*) public_key->data;
	i2d_PublicKey(pkey, &p);

exit:
	if (pkey)
		EVP_PKEY_free(pkey);

	return success;
}
