Cryptography
 

I am thinking about making an encryption program in C++. I know little about cryptography and even less about how to implement a good encryption method with programming. Does anyone know of a encryption method, that would be very difficult to crack that could be used to encrypt plain text files.

I would suggest that you do some research in the cryptographic area. True, secure cryptography is not a trivial subject. Experts who have been doing it for years still often get it wrong when devising new techniques.

Lots of programmers dip their toes in the water from time to time, but the result is (predictably) mostly junk, which runs counter to your stated requirement.

Have you Googled this subject at all?

I dug around alittle. But all I found is a bunch of unsecure methods, that could be crakced with a little playing around.

Did you look into the Advanced Encryption Standard?
http://en.wikipedia.org/wiki/Advance...ption_Standard

The National Security Agency has approved it for the encryption/decryption of SECRET and TOP SECRET government data when used with 192 or 256 bit key lengths. I would surmise that such an algorithm would be sufficient for your project.

But the question is: can the government crack it? Just kidding :icon_cheesygrin:

Looks good. Just got get a manual on this stuff. Hope it isn't hard to use.

Edit:
Yeah, this manual isn't helping. I need help on this.

Try reading Applied Cryptography by Bruce Schneier, I heard some good things about it. I actually purchased it this week from my local charity shop (£5.99, it was a bargain)

I rather not pay for information. I'll just dig around more. Thanks for pointing me in the right direction guys. ;)
