md5加密dll
‘壹’ MD5做成DLL插件加密安全嘛
楼上是SB
加密三次可以的了，想知道加密多少次要费很多时间，解密的不一定知道是用MD5加密的啊，你如果还不肯定安全不，你可以第一次加密后取中间几位数再加密一次这样就更安全了。
‘贰’ delphi 中的 MD5 加密怎么用
1.在Delphi自带的Indy控件中其实是提供了MD2,MD4,MD5对象的，可以直接使用来完成MD5的签名算法。不需要DLL或是Pas。 2.在Uses单元中引用 IdHashMessageDigest,IdGlobal, IdHash 单元，再写如下代码即可以达到MD5的实现。
‘叁’ C#中dll该如何声明及调用
[DllImport("twain_32.dll", EntryPoint="#1")]
private static extern TwRC DSpxfer( [In, Out] TwIdentity origin, [In] TwIdentity dest, TwDG dg, TwDAT dat, TwMSG msg, [In, Out] TwPendingXfers pxfr );
[DllImport("kernel32.dll", ExactSpelling=true)]
internal static extern IntPtr GlobalAlloc( int flags, int size );
‘肆’ 帮忙破解一个MD5,
帮你跑了，没跑出来。。。。。。。
不过给你提供一个方法，来破解绿坝：
绿坝的管理密码，通过类似于MD5的加密之后，储存在WINDOWS/system32/kwpwf.dll文件中，搞笑的是该文件并没有收到任何程序的保护，单凭一记事本就可以大改其中内容。我们只要把知道密码的绿坝的WINDOWS/system32/kwpwf.dll文件中的内容复制到不知道密码的那个绿坝的WINDOWS/system32/kwpwf.dll下，就相当于改变其密码了。也就是说，我们只要把WINDOWS/system32/kwpwf.dll的内容改为“”，那么绿坝的管理密码就变回了默认的112233。
也就是说你破解它的时候，就将此MD5散列""替换掉原先的，不用的时候在替换回去即可~
希望对你能有所帮助。
‘伍’ 求md5批量加密的工具，要能保存加密出来的密文，密文与明文对应的....生成数据库也行！
