Title: An Illustrated Guide to Cryptographic Hashes Post by: Severian on February 25, 2013, 05:34:59 PM Pardons if this is a repeat. Some of the new folks might get something out of it if they're unfamiliar with the concepts.

This is a great read to those who are confused about encryption and hashes. (although it's perhaps just a tad too easy) :) Title: Re: An Illustrated Guide to Cryptographic Hashes Post by: Severian on February 26, 2013, 06:53:10 AM Quote Guvf vf n terng ernq gb gubfr jub ner pbashfrq nobhg rapelcgvba naq unfurf. "This is a great read to those who are confused about encryption and hashes." OTP is the only way to cipher. : ) Title: Re: An Illustrated Guide to Cryptographic Hashes Post by: Severian on February 26, 2013, 06:54:35 AM (although it's perhaps just a tad too easy) Blast.

If you like your guide to cryptographic hashes to be less illustrated, and written by crypto experts: http://cacr.uwaterloo.ca/hac/about/chap9.pdf More reading applicable to Bitcoin would be chapter 11 on digital signatures (here, just get the whole book:). Handbook Of Applied Cryptography (Mit Press).pdf (http://people.grenouille.com/~fraggle/books/Handbook%20Of%20Applied%20Cryptography%20%28Mit%20Press%29.pdf) Note, ECDSA is merely a footnote in this text, you can build on your knowledge in this order: Intro to Elliptic Curve Crypto: http://www.fujitsu.com/downloads/MAG/vol36-2/paper05.pdf A longer history: http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.215.1721&rep=rep1&type=pdf and the initial paper on ECC: http://www.ams.org/journals/mcom/1987-48-177/S0025-5718-1987-0866109-5/S0025-5718-1987-0866109-5.pdf Then try chapter 6 of Course in Number Theory and Cryptography - Koblitz (http://www.2shared.com/document/Zw_qf65G/Course_in_Number_Theory_and_Cr.html) (zee pirate link) If you want to understand the above, have some graduate mathematics prerequisites: Algebraic Geometry: http://www.math.lsa.umich.edu/~wfulton/CurveBook.pdf Elliptic curves and modular forms: http://w3.impa.br/~hossein/courses/material/arithmetic.pdf |
