我想在我的程序中只使用aes。我複製文件只能從Polarssl運行aes的文件
- 的config.h
- aes.h
- havege.h
文件夾polarssl。但是,當我運行程序
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "polarssl/aes.h"
#include "polarssl/havege.h"
int main()
{
char buff[2][64] = {"ABCDEFGHIJKLMN", ""};
havege_state hs;
int retval;
unsigned char IV[16];
unsigned char IV2[16];
unsigned char key[32];
aes_context enc_ctx;
aes_context dec_ctx;
havege_init(&hs);
havege_random(&hs, IV, 16);
havege_random(&hs, key, 32);
strncpy(IV, IV2, 16); //copy IV
aes_setkey_enc(&enc_ctx, key, 256);
aes_setkey_dec(&dec_ctx, key, 256);
//encrypt
aes_crypt_cbc(&enc_ctx, AES_ENCRYPT, 64, IV, buff[0], buff[1]);
printf("Before encrypt:%s\n", buff[0]);
//decrypt
aes_crypt_cbc(&dec_ctx, AES_DECRYPT, 64, IV2, buff[1],buff[0]);
printf("After decrypt:%s\n", buff[0]);
return 0;
}
我收到錯誤
