this repo finished a DES ECB encrypt/decryption method. for now just DES/EBC is tested. more test and pull request is welcomed.
this Tencent qcloud HTTPDNS servier DES ECB padding5 encryption API,where you can verify you result http://119.29.29.29/en?v=www.google.com&k=weijianliao key: weijianliao result: cd52888ecabcac455a14ddbac7f03d97
you can just test with resty CLI
root@localhost:~# resty lua_func_test.lua
cd52888ecabcac455a14ddbac7f03d97
decode:www.google.com
example in Java
try {
//init key
SecretKeySpec keySpec = new SecretKeySpec(encKey.getBytes("utf-8"), "DES");
//choose DES £¬ECB mode£¬ PKCS5Padding
Cipher cipher = Cipher.getInstance("DES/ECB/PKCS5Padding");
//init
cipher.init(Cipher.ENCRYPT_MODE, keySpec);
//get encrypted string
encryptedString = bytesToHex(cipher.doFinal(hostName.getBytes("utf-8")));
} catch (Exception e) {
e.printStackTrace();
}
example code in PHP
/**
* des-ecb½âÃÜ
* @param string $data data need encrypted
* @param string $key encrypted key
*/
function des_ecb_decrypt ($data, $key){
return openssl_decrypt ($data, 'des-ecb', $key);
}
$str = 'www.google.com';
$key = 'weijianliao';
$res = des_ecb_encrypt($str, $key);
echo bin2hex(base64_decode($res))."\n";
// result is=cd52888ecabcac455a14ddbac7f03d97
