    Question

    Does anyone know where I can find information regarding the implementation of good encryption in VB? I need to secure very sensitive information.

    Information on a RC4 implementation would be ideal, or something to that degree...

    There is an algoritmencryption and a keyencryption on my homepage, the keyencryption should be secure enough for you
    Use
    writing software in C++ is like driving rivets into steel beam with a toothpick.
    writing haskell makes your life easier:
    reverse (p (6*9)) where p x|x==0=""|True=chr (48+z): p y where (y,z)=divMod x 13
    To throw away OOP for low level languages is myopia, to keep OOP is hyperopia. To throw away OOP for a high level language is insight.

    Yes, I have an example of RC4 Encryption. I will look for it and post it up soon.

    Yes, but it isn't RC4.

    I've tested it out, it's much slower than mine.
    My code is not copyright protected either, use it and you don't even have to credit me (Although i would appreciate that) Keyencryption is more secure the longer your key is, so you can adjust it yourself, (shouldn't drain on performance)

    If you would like some more examples which do not require a license, go to http://www.planet-source-code.com and type in RC4 and press search. It will give you many pages full of free examples.

    Lightbulb CryptEncrypt API

    May be this the good time for you to study the Cryto API function : CryptEncrypt

    You can get more info and example from the following URL
