Examples
To help you get started with OpenSSL-AIS, we’ve provided some code examples below:
Example 1: Symmetric Encryption
#include <openssl-ais/aes.h>
#include <openssl-ais/modes.h>
...
// Use AES-256 to encrypt data with a given key and IV
AES_KEY key;
unsigned char iv[AES_BLOCK_SIZE];
// Initialize key and IV
unsigned char plaintext[1024];
int plaintext_len;
unsigned char ciphertext[1024];
int ciphertext_len;
// Encrypt the plaintext
AES_set_encrypt_key(key, 256, &key);
AES_cfb128_encrypt(plaintext, ciphertext, plaintext_len, &key, iv, &num, AES_ENCRYPT);
...
Example 2: Digital Signatures
#include <openssl-ais/rsa.h>
#include <openssl-ais/sha.h>
#include <openssl-ais/evp.h>
...
// Generate RSA private and public keys
RSA *rsa = RSA_generate_key(2048, RSA_F4, NULL, NULL);
...
// Sign the message using RSA private key and SHA-256 hash
unsigned char message[1024];
int message_len;
unsigned char signature[1024];
unsigned int signature_len;
// Hash the message using SHA-256
unsigned char hash[SHA256_DIGEST_LENGTH];
SHA256(message, message_len, hash);
// Sign the hash
RSA_sign(NID_sha256, hash, SHA256_DIGEST_LENGTH, signature, &signature_len, rsa);
...
