使用源码

// 加密算法
    public static function encrypt($input, $key) {
        $size = mcrypt_get_block_size ( 'des', 'ecb' );
        $td = mcrypt_module_open ( MCRYPT_3DES, '', 'ecb', '' );
        $iv = @mcrypt_create_iv ( mcrypt_enc_get_iv_size ( $td ), MCRYPT_RAND );
        // 使用MCRYPT_3DES算法,cbc模式
        @mcrypt_generic_init ( $td, $key, $iv );
        // 初始处理
        $data = mcrypt_generic ( $td, $input );
        // 加密
        mcrypt_generic_deinit ( $td );
        // 结束
        mcrypt_module_close ( $td );
        
        return $data;
    }
    public static function decrypt($encrypted, $key) {
        //$encrypted = base64_decode($encrypted);
        $td = mcrypt_module_open ( MCRYPT_3DES, '', 'ecb', '' ); // 使用MCRYPT_DES算法,cbc模式
        $iv = @mcrypt_create_iv ( mcrypt_enc_get_iv_size ( $td ), MCRYPT_RAND );
        $ks = mcrypt_enc_get_key_size ( $td );
        @mcrypt_generic_init ( $td, $key, $iv ); // 初始处理
        $decrypted = mdecrypt_generic ( $td, $encrypted ); // 解密
        mcrypt_generic_deinit ( $td ); // 结束
        mcrypt_module_close ( $td );
        //$y = TDESUtil::pkcs5Unpad ( $decrypted );
        return $decrypted;
    }
