1. Finish discussion of symmetric key encryption.
Some concepts to discuss :
- CBC : cipher block chain, and IV - initial vector
- CTR : encrypt(nonce + increment) xor plain
- DES : digital encryption standard (deprecated)
- AES : a common choice these days
I've also attached a text file with some notes.
2. hash algorithms
3. start public/private key algorithms; see how time goes.
