Is there any example on how to use HMAC SHA1 and PBKDF2 SHA1 under oneAPI in SYCL? I found just the basic HMAC description here.
AI generated for me:
Generate C++ HMAC SHA1 fucntion by using oneAPI functions: HMAC_GetSize , HMAC_Init, HMAC_Update , HMAC_GetTag , HMAC_Final.
#include <iostream>
#include <cstring>
#include <oneapi/tbb.h>
#include <oneapi/crypto.h>
int main()
{
const char* key = "my-secret-key";
const char* data = "data-to-hash";
oneapi::crypto::key_256bit hmac_key;
std::memcpy(hmac_key.data(), key, std::min(sizeof(hmac_key), strlen(key)));
int hash_size = oneapi::crypto::HMAC_GetSize(oneapi::crypto::algorithm::sha1);
std::vector<uint8_t> result(hash_size);
oneapi::crypto::HMAC_Init hmac_init(oneapi::crypto::algorithm::sha1, hmac_key);
oneapi::crypto::HMAC_Update hmac_update(hmac_init, data, strlen(data));
oneapi::crypto::HMAC_Final hmac_final(hmac_update, result.data(), result.size());
for (int i = 0; i < hash_size; ++i)
{
printf("%02x", result[i]);
}
std::cout << std::endl;
return 0;
}
Generate C++ PBKDF2 SHA1 function by using oneAPI libraries.
#include <iostream>
#include <oneapi/crypto.h>
#include <oneapi/tbb.h>
int main()
{
const char* password = "my-strong-password";
const uint8_t* salt = (uint8_t*)"my-random-salt";
int salt_len = strlen((const char*)salt);
int iterations = 4096;
int key_len = 32;
std::vector<uint8_t> key(key_len);
oneapi::crypto::PBKDF2_HMAC_SHA1(password, strlen(password),
salt, salt_len,
iterations,
key.data(), key_len);
std::cout << "Derived Key: ";
for (int i = 0; i < key_len; i++) {
printf("%02x", key[i]);
}
std::cout << std::endl;
return 0;
}
