An Illustrated Guide to Cryptographic Hashes

Pardons if this is a repeat. Some of the new folks might get something out of it if they're unfamiliar with the concepts.

nice find, thanks

See if you can decrypt my latest encryption algorithm..

This is a great read to those who are confused about encryption and hashes.

(although it's perhaps just a tad too easy)

"This is a great read to those who are confused about encryption and hashes."

OTP is the only way to cipher. : )

Blast. Quick shooting there, pard. : )

But note: though we're fairly strong on security issues, we are not crypto experts.

If you like your guide to cryptographic hashes to be less illustrated, and written by crypto experts:

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

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 (zee pirate link)


If you want to understand the above, have some graduate mathematics prerequisites:
Algebraic Geometry:

Elliptic curves and modular forms:
