AES 加密 PHP 和 JAVA 互通

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);
    $td = mcrypt_module_open(MCRYPT_RIJNDAEL_128, '', MCRYPT_MODE_ECB, '');
    $iv = mcrypt_create_iv (mcrypt_enc_get_iv_size($td), MCRYPT_RAND);
    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 );
