AES加密(PHP)
最近在工作中遇到了AES加密,第一次用这个加密,经过摸索解决了我的问题,所以记录一下,分享一下。(不喜勿喷!!!)
废话少说直接上代码:
<?php
class aes{
/**
* 通过AES加密请求数据
*
* @param array $query
* @return string
*/
function AESEncryptRequest($encryptKey, $query){
return $this->encrypt_pass($query,$encryptKey);
}
// 加密
function encrypt_pass($input, $key) {
$size = mcrypt_get_block_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC);
$input = $this->pkcs5_pad($input, $size);
$td = mcrypt_module_open(MCRYPT_RIJNDAEL_128, '', MCRYPT_MODE_CBC, '');
$iv = '0102030405060708';
mcrypt_generic_init($td, $key, $iv);
$data = mcrypt_generic($td, $input);
mcrypt_generic_deinit($td);
mcrypt_module_close($td);
$data = base64_encode($data);
return $data;
}
//填充
function pkcs5_pad ($text, $blocksize) {
$pad = $blocksize - (strlen($text) % $blocksize);
return $text . str_repeat(chr($pad), $pad);
}
/**
* 通过AES解密请求数据
*
* @param array $query
* @return string
*/
function AESDecryptResponse($encryptKey,$data){
return $this->decrypt_pass($data,$encryptKey);
}
// 解密
function decrypt_pass($sStr, $sKey) {
$iv = '0102030405060708';
$decrypted= mcrypt_decrypt(
MCRYPT_RIJNDAEL_128,
$sKey,
base64_decode($sStr),
MCRYPT_MODE_CBC,
$iv
);
$dec_s = strlen($decrypted);
$padding = ord($decrypted[$dec_s-1]);
$decrypted = substr($decrypted, 0, -$padding);
return $decrypted;
}
}
