函数源码
复制代码 代码如下:
function encrypt($data, $key) {
$prep_code = serialize($data);
$block = mcrypt_get_block_size(''des'', ''ecb'');
if (($pad = $block - (strlen($prep_code) % $block)) < $block) {
$prep_code .= str_repeat(chr($pad), $pad);
}
$encrypt = mcrypt_encrypt(MCRYPT_DES, $key, $prep_code, MCRYPT_MODE_ECB);
return base64_encode($encrypt);
}
function decrypt($str, $key) {
$str = base64_decode($str);
$str = mcrypt_decrypt(MCRYPT_DES, $key, $str, MCRYPT_MODE_ECB);
$block = mcrypt_get_block_size(''des'', ''ecb'');
$pad = ord($str[($len = strlen($str)) - 1]);
if ($pad && $pad < $block && preg_match(''/'' . chr($pad) . ''{'' . $pad . ''}$/'', $str)) {
$str = substr($str, 0, strlen($str) - $pad);
}
return unserialize($str);
}
调用函数
复制代码 代码如下:
$key = ''okyo.cn'';
$data = array(''id'' => 100, ''username'' => ''customer'', ''password'' => ''e10adc3949ba59abbe56e057f20f883e'');
$snarr = serialize($data);
$en = encrypt($data, $key);
$de = decrypt($en, $key);
echo "加密原型:";
print_r($data);
echo "
密钥:$key
加密结果:$en
解密结果:";
print_r($de);
