SSL isn't good enough. Your website can be hacked.
Help solve the problem by advocating these RFCs:

TLSA (formerly DANE for DNS) Fixes the hackable CA problem

TLS-OBC: Fixes TLS, and the Related Domain Cookie Attack

I have no relation to the above sites; I am just an advocate

Why "makerofthings7"? It's a challenge to "make seven things in my life of significant quality and value". Who knows if those things will take the form of software, art, or people. (I'm not married, no kids yet)

comment Can Secp 256 K1 curves “map” to a value on FIPS 186-3 or P-256?
Fundamentally, I want to use UProve crypto material in Bitcoin transactions.

FYI the link to PRNG has been updated, and it seems it will be revised again soon after public comment. Here are the interim links: SP800-90A and the public drafts

I will look more into group structures and group orders as you mention... but if instead of P-256, could any interesting maps be made with field based subgroups FIPS 186-3 and Secp 256 K1?

@CodesInChaos I don't know how to even begin to define equivalence in curves. Could FIPS 186-3 be equivalent?

@RichieFrame UProve also uses a subgroup variant which is FIPS 186-3 finite field based DSA. Would that mean a mapping is possible

What information would be in that attribute? Is it encrypted data?

comment How can I tell which curve a given ECDSA implementation uses? (P-521 or something else)
I just purchased that $99 book the other day. Glad to know I have the right study material. Thanks for confirming that, and let me know if you come across anything else I should know

comment How can I tell which curve a given ECDSA implementation uses? (P-521 or something else)
I'd like to study the equation 'y^2 = x^3 + ax + b` in more depth. Where should I begin? (how are those variables generated, what are known weaknesses, etc?)
