Would you please send me some encryption and decryption algorithm or source code?

Hello:

I need the source code(or algorithm,better for source code) of Message Digest ,Encryption and decryption ?

thanks a lot.

sm_ch,

Search for "md5". Google turned up 1.4 million hits with the first
one providing source code.

...or OpenSSL. It includes MD5, SHA-1, RSA, DES, AES, and many many more...

The "best" encryption currently is Rijndael or the Advanced Encryption Standard. It's name is derived from the name of the (Belgian) inventors. Click here for implementations in C/C++ and assembler. It's not proven to be "uncrackable" (all algorithms are if you try all keys) though.

You are so kind.

Thanks a lot.

I have another problems to ask you:

maximum length of MD5's result.
RSA's parameters.
And I need to develop a server application and a client application.

the client application reads IE's message,inserts some message from local PC before the whole message from IE,then I use MD5 to get their digest message, insert the digest before again,last I encrypted it with RSA public key from server.

the server application read the message from client application ,processes it and send the result to ASP pages.

Now my way is that the server application receives the message from client application,processes it and send it to 80 port which is the HTTP port.But you know people can connect to 80 port directly.If I can not make the server application be the bridge between IE and ASP pages I will have to do more jobs.
