Does anyone know of a good (and preferably well documented) free library for public/private key encryption? Just needs to generate keys and do the encryption/decryption given the keys. Thanks, ~SPH

Well, it's doing everything then?

I know of Crypto++.
If you are working exclusively on Windows, there is also CryptoAPI.

[edit] I have used neither, so I cannot comment on their relative merits.

You'd think that that was everything, but most libraries that I've come across try to do much more... like manage the keys, maintain user databases, act as a sockets layer, and raise your first born child :)

Thanks though, I'll take a look at those, ~SPH

I would also look at OpenSSH and friends. As you say, these libraries commonly do a lot more, but you can typically strip out what you don't need. Or just let it sit on the hard disk, never being paged in :-)

There's is also tomcrypt you could check out as well.
