Encryption Project...

I'm making an encryption/decryption project and would like suggestions on algorithms to . implement. RSA, One-time pad, and DES are a must..

EDIT: I'm also making an enigma (M3 + M4 editions) side-project

Re: Encryption Project...

Have you heard of the Playfair cypher? That one is a great one, but it might be hard to program. One time pad is a good one, i definately agree. It would be cool if you could somehow make an enigma machine that you could change the settings on.

This is a really cool idea!  tongue

Re: Encryption Project...

You could try this md5 algorithm

Not sure if its possible in scratch though

Hmmm...  Looks interesting

Re: Encryption Project...

@Archmage MD5 is a (weak)hash algorithm, used for just making a "Signature" of data to tell if a transmission has been modified since it's departure.
@greenflash Playfair cipher is simple, I can do it. As for the enigma, that is a side project i'm working on.
