Can any1 please suggest me some links from where I could buy ocx or dll's that i could use to add in a mechanism in my vb6 project to encrypt binary files using SHA-1 or higher

"actually i just need to hash the binary file so that after transferring it i can check to c if both the file copies match....
is that what the SHA algorithm does?....... will it help me verify whether its the correct and uncorrupted file? - clairh 16 hours ago"

Yes, that is one use. You don't need to buy anything - SHA is built in to .NET
Look at http://msdn.microsoft.com/en-us/library/system.security.cryptography.sha512managed.aspx for details.

Solution 1

SHA is not an encryption algorithm. It is a hashing algorithm.
The difference is that encrypted code can be decrypted. Hashed code cannot be unhashed to produce the original inputs.
If you create an SHA code for your binary file you cannot go back to the file from the SHA code.
