The Octalforty Exile application was developed to be a small password manager.

In the beginning, I've spent some time looking for a suitable encryption algorithm (at that time, I didn't even suppose that I'll also need a hashing algorithm - lack of planning and stuff...).

I decided in favor of RC5 - a symmetric block cipher, which was said to be fast and secure. Initially, I wanted to write some kind of CRC5 class but (mostly for the hell of it) I decided to turn it into a separate fancy-looking DLL with some kind of API (contexts, handles and so on...).

Then I started to think about how the program itself will look like. The idea of storing User name and Master password in the password storage itself seemed perfidious, so I understood that some hashing algorithm is required and I fixed upon MD5, invented by the tireless Professor Ronald R. Rivest. As with RC5, a simple CMD5 class turned into a standalone DLL. So here's what I decided to implement.

- Store a + hash in a password storage and compare with the hash of + entered when attempting to open a storage.
- Generate a private key by repeatedly hashing + + so that knowing + combination hash doesn't guarantee successful cracking.
- When loaded, all sensitive information remains encrypted until it is shown on the screen.
