Hi,
I am planning to write a Encription Utility which will be able to encrypt/decrypt any types of file. I am new to encription, so i would like to hear from u guys. Like what are the algorithm available and which is the best. And is it possible to write a Encription Tool in VB.
Thanks for any help

You should do a standard web search using 'encryption coding' or 'programming' as search phrase.
Any search engine will give you loads of sites that deal with this.
Look at the MS encryption API as well.
Of course you can do this with VB - you can do it any prog. langage.
Go to http://www.planet-source-code.com and search for "encryption". One I find that works well is RC4.
If you want to make your own encryption method you could go to my homepage and download examples on keyencryption
Hi,
Thanks everyone for your reply. Can any one tell me how can i Encrypt a file rather then text. I want to write a function which will take a filename (anytype) as a parameter and encrypt the passed file. How do i go about it, any ideas.
Thanks again

Search for RC4, as Megatron said. It is a file encryptor (for all file types including exe).
In other words, a Binary encryptor. It encrypts regardless of whether it's a string or numeric.
Open the file in binary, Read the file with Get statement into a byte array, perform the encryption on the array, use Put statement to write the array back to the file. Now the encryption part is up to you or?
You could use Cipher encrypting, same as RC4, which will encrypt any type of file. Click Cipher and you will see a few things on it from http://www.planet-source-code.com.
Hi Guys,
Thanks againg, u been a great help, i already have a better understanding of Encryption. I and currently looking at some source code from Planet-Source-code.
