Java 算法需求

使用openssl進行AES/CBC/PKCS5Padding加密

問題解決了。

@openssl_encrypt($data, 'AES-128-CBC', $Key,OPENSSL_RAW_DATA);

iv不填寫直接加密，這樣子就行了
不過php會出現(xiàn)warning，在前面加一個@就可以了

php7 版 示例
ase.php

  <?php


namespace app\admin\model;


class Ase
{

    /**
     * [encrypt aes加密]
     * @param    [type]                   $input [要加密的數(shù)據(jù)]

     * @return   [type]                          [加密后的數(shù)據(jù)]
     */
    public static function encrypt($input, $key)
    {
        $key = self::_sha1prng($key);
        $iv = '';
        $data = openssl_encrypt($input, 'AES-128-ECB', $key, OPENSSL_RAW_DATA);

    }

        return $decrypted;
    }

    /**

    private static function _sha1prng($key)

        return substr(openssl_digest(openssl_digest($key, 'sha1', true), 'sha1', true), 0, 16);
    }

    /**

    private static  function url_safe_b64encode($string) {
        $data = base64_encode($string);
        $data = str_replace(array('+','/','='),array('-','_',''),$data);
        return $data;
    }

    /**
     * url base64解碼

     * @return false|string
     */
    private static function url_safe_b64decode($string) {
        $data = str_replace(array('-','_'),array('+','/'),$string);
        $mod4 = strlen($data) % 4;
        if ($mod4) {
            $data .= substr('====', $mod4);
        }
        return base64_decode($data);
    }
}

使用文件

        $jsonData = json_encode($data, JSON_UNESCAPED_UNICODE); //數(shù)組轉(zhuǎn)json Utf-8
        $appKeyHash = md5(self::$appKey);
        $checkCodeHash = md5($jsonData . self::$apiCode . self::$appKey);
        $jsonDataAES = Ase::encrypt(urlencode($jsonData), self::$appKey);
