Re: Deterministic Usage of DSA and ECDSA Digital Signature Algorithms (RFC 6979)
Wow, thanks for posting your 'microecdsa' code - now I get to see how what I came up with stacks up to your version 
Couple questions:
Is the algo you created resistant to side-channel attacks (constant time for doing the scalar multiply)?
Can you give me any insights/references into your 'PRECOMPUTED_CP/IV' technique?

Btw, slush and I are trying to implement RFC6979 into python-ecdsa/microecdsa. Hopefully we'll publish the results soon (or watch https://github.com/trezor/python-ecdsa and https://github.com/trezor/microecdsa repos).
