AES 加密 PHP 和 JAVA 互通

见代码:

 

PHP代码:

 

<?php

class Security {

public static function encrypt($input, $key) {

$size = mcrypt_get_block_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_ECB);

$input = Security::pkcs5_pad($input, $size);

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;

}

 

private static function pkcs5_pad ($text, $blocksize) {

$pad = $blocksize - (strlen($text) % $blocksize);

return $text . str_repeat(chr($pad), $pad);

}

 

public static function decrypt($sStr, $sKey) {

$decrypted= mcrypt_decrypt(

MCRYPT_RIJNDAEL_128,

$sKey,

base64_decode($sStr),

MCRYPT_MODE_ECB

);

 

$dec_s = strlen($decrypted);

$padding = ord($decrypted[$dec_s-1]);

$decrypted = substr($decrypted, 0, -$padding);

return $decrypted;

}

}

 

 

 

$key = "1234567891234567";

$data = "example";

 

$value = Security::encrypt($data , $key );

echo $value.'<br/>';

echo Security::decrypt($value, $key );
