需要写一个小程序 能转移会员的资料
需要读出会员的密码
找到人家写的一段java的程序
但是我看不懂

我只会vb 对java一点都不懂
哪位大哥大姐能帮我翻译一下啊

我先知道这个加密算法
然后我用vb来写出来

看到里面好像要调用一个a.dll

希望得到你们的帮助
万分感谢

楼主只要把会员密码代入getEncryptString进行解密即可，解密算法用的是Java本身写好的64位算法，楼主只要找到64位VB解密算法即可。

能将这两句语句给翻译一下吗
用白话翻译也可以啊
BASE64Decoder BASE64Decoder = new BASE64Decoder();
s1 = new String(n.a()._mthif(BASE64Decoder.decodeBuffer(s)));

字符串 “ ETLCw4cN ” 用java得到的结果是 123456

用其他语言经过base64编码以后的结果是 2旅?

不知道问题到底出在哪里

字符集不统一吧。
