Discussion Overview

The discussion centers around the fundamental methods of cryptography, specifically asymmetric and symmetric cryptography. Participants explore the existence of formulas related to cryptographic systems and the complexity of the field, touching on historical and modern approaches to cryptography.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant asserts that there are two fundamental ways of cryptography: asymmetric and symmetric, and inquires about the existence of formulas for encryption systems.
  • Another participant suggests that if a formula exists, it could eventually be discovered and used to break the cipher, referencing historical reliance on physical duplication of random keys.
  • A different participant emphasizes the complexity of cryptography, stating that it cannot be summed up in one equation and recommends a book by Simon Singh for insights into the history and development of cryptographic systems.
  • One participant mentions that there are many forms of cryptography and recommends Bruce Schneier's "Applied Cryptography" for practical tools and algorithms.
  • Another participant critiques Schneier's book for lacking depth in explaining why certain systems are used, suggesting alternative texts for a more mathematical perspective on cryptography.

Areas of Agreement / Disagreement

Participants express differing views on the complexity of cryptography and the adequacy of various resources for understanding the field. There is no consensus on the best approach to learning about cryptography or the existence of a definitive formula.

Contextual Notes

Participants highlight the limitations of certain texts in providing comprehensive explanations of cryptographic systems and their applications, indicating a dependency on the reader's background and the specific focus of the resources mentioned.

i know that there are 2 fundmental ways of cryptography

asymeteric and symeteric

is there any formulas for cryptography? i know its for a encryption system, but there must be formulas?

thanks

If there is a formula, eventually someone else will discover what it is and break your cipher. Historically the best cryptograms have been based on physical duplication of random keys (one time pads).
 
Cryptography is a complex field, you can't really sum up the methods of it in one equation (At least I can't), but there's an excellent book available by Simon Singh that's called "The Code Book" that tells you how cryptography was invented, how it was developed, how the modern cryptography systems work (The RSA system) and what people think will replace RSA in the future. It's very interesting, there's not much math to follow, the math isn't hard and it's a very good read.
 
There are actually lots of forms of cryptography.

If you actually want algorithms and practical tools to build cryptographic systems, forget paperbacks. The best book, IMO, is Bruce Schneier's "Applied Cryptography."

Schneier's book doesn't tell you why the systems are used that way, infact it just tells you in a rather coarse way to "do this and do that"...

Try "Modern Cryptography: Theory and Practice" by Wenbo Mao
or "Cryptography" by Nigel Smart for a more mathematical look on crypto.
