AES implementation code
Jul 14, 2022 18:31
I tried implementing AES functions but also after reading the SDK and a lot of trials, several things are not clear.
How should I pass the string to be encrypted to aes_encrypt? As char array containing char(s) o char array containint equivalent hexadecimal numbers?
The resulting char array contains char(s) or hexadecimal numbers?
I've already tried to encrypt a string and then decrypt it both with different online tools (set with AES128 ECB) and with aes_decrypt, and I can never get back the original string.
Has anyone got a piece of code that can be used as example?
Thank you!
Hi,
char key[17] = "ciaociaociaociao";
char data[17];
char chypertext[17];
int check ;
char plaintext[17];
void main_loop (void)
{
check = aes_encrypt(key, data, chypertext);
check += aes_decrypt(key, chypertext, plaintext);
sleep_ms(500);
gpio_toggle(LED1|LED2|LED3|LED4);
}
we test it on this link(https://the-x.cn/cryptography/Aes.aspx) is fine,you can use translation software to use .
Thank you!
