Encryption algorithm [closed]

Do you know a good encryption algorithm that isn't too开发者_运维技巧 difficult to implement in c++ (but neither too easy)?

Look at this wonderful comics on AES. It explains the cryptographic background of the algorithm and you can practice by writing a high-performance implementation of one in different languages.

I think RSA is good as well as pretty much straightforward to implement. You might want to look into it. Another one I would be suggesting which is also straightforward is DES.

• Rivest, Shamir and Adleman (RSA)
• Data Encryption Standard (DES)

If you're just looking for something to code up for the learning experience, I've always liked the Advanced Encryption Standard. The actual standard document at NIST provides all the detail you need to write and test your code.

I like RC5 for its simplicity. Much easier to implement than e.g. AES, and while not quite as strong, it is still a good cypher.
