爆汗,加密有还要是数字啊????
你自己写一个吧,比如把一个你的数字*xxx+yyy-zzz,反正你要求也简单

谢谢你，不过加密后的效果能不能还是数字啊

sureyor 老兄提供的可以加密，但加密后的结果是还是数字就好了

我不需要明白算法，只需要在JS中调用。实现数字加密(可逆)，就可以了.希望大家能够帮助我

是啊，我想是大侠们能够给我提供一个方法，实现数字加密（可逆的）

LS两位大哥是不是理解错了？LZ是想用js实现个算法，可以对数字加密。你们给的好像是怎么样把js代码搞复杂让人看不懂吧？还是我理解错了？？？
我主要是觉得LZ你用个js写个加密解密，算法不是也在客户端暴露着么？就算你把js搞的很复杂很难懂，可是就算不搞懂代码，只需要调用你的解密方法就行了吧？
