Cryptography…

December 2, 2012

food for thought… I can’t comment since I’m an absolute beginner as a first semester cybersecurity student – but I’m reading as much as I can!

Holy Hash!

Software developers regularly attempt to create new encryption and hashing algorithms, usually to speed up things. There is only one answer one can give in this respect:

What part of "NO" don't you understand?

Here is a short summary of reasons why you should never meddle in cryptography.

  1. Cryptography is mathematics, very advanced mathematics
  2. There are only a few good cryptographers and cryptanalysts and even they get it wrong most of the time
  3. If you are not one of them, never, ever, ever try to write your own cryptographic routines
  4. Cryptography is a very delicate matter, worse than bomb defusing
  5. Consequently you must know that most usual “cryptographic” functions are not
  6. Even when it is good, cryptography is too easy to abuse without knowing it
  7. Bad cryptography looks the same as good cryptography. You will not know whether cryptography is broken until it is too late

So, I hope you are sufficiently convinced not to create…
