当时我拿到了这段username=admin&password=admin&code=123123&isMandatory%5BisTrusted%5D=true的密文，第一次解密的时候是没有经过这个插件来对以上字符串加密的（密钥和偏移量都给对了），提示not found，然后我使用这个插件对上面这段字符进行加密之后（加密后和原来js加密的一致的），再来对刚才提示not found的那段密文进行解密就能解出来，但是没有加密之前就不能解出来

这个是“Get PlainText”的设计逻辑导致的，这个功能不具备“解密”功能，之所以你能通过加密后重新"解密"获取原始明文，其实是因为这是通过本地的K/V数据库查询得到的。目前由于部分算法产生的结果具有不可逆性（哈希算法、自定义的JS代码等）所以暂未确定具体解密的代码逻辑，所以也暂时不具备直接解密功能。之前也有师傅问过类似的问题 #13
