PHP 使用 mcrypt 进行加密解密的函数

2. // Encrypt Function
3. function mc_encrypt($encrypt, $mc_key) {
4. $iv = mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB), MCRYPT_RAND);
5. $passcrypt = trim(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $mc_key, trim($encrypt), MCRYPT_MODE_ECB, $iv));
6. $encode = base64_encode($passcrypt);
7. return $encode;
8. }
10. // Decrypt Function
11. function mc_decrypt($decrypt, $mc_key) {
12. $decoded = base64_decode($decrypt);
13. $iv = mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB), MCRYPT_RAND);
14. $decrypted = trim(mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $mc_key, trim($decoded), MCRYPT_MODE_ECB, $iv));
15. return $decrypted;
16. }
17. ?>
