Jochen Hoenicke	157caf3763	ecdsa: fix out-of-bounds read in point_multiply (#71) ... Fixes #70.	2016-10-06 16:54:25 +02:00
Jochen Hoenicke	133c068f37	Reworked rfc6979 signing. (#72) ... This adds an is_canonic parameter to all sign functions. This is a callback that determines if a signature corresponds to some coin specific rules. It is used, e. g., by ethereum (where the recovery byte must be 0 or 1, and not 2 or 3) and or steem signatures (which require both r and s to be between 2^248 and 2^255). This also separates the initialization and the step function of the random number generator, making it easy to restart the signature process with the next random number.	2016-10-06 16:54:07 +02:00

Jochen Hoenicke	19a1f501c4	Simplified sha256_Final/sha512_Last ... - Fix the bug where we zero too many bytes in sha512_Last (SHORT_BLOCK_LENGTH != BLOCK_LENGTH -2). - Get rid of an if branch. - Don't reverse the last two words in 512_Last that are written later. - make 256_Final and 512_Last look the same.	2016-08-29 21:55:57 +02:00

Pavol Rusnak	3661b04936	Merge pull request #64 from spudowiar/ignore-dependency-generation ... Add generated dependency files to .gitignore	2016-08-22 11:07:37 +02:00
Saleem Rashid	a17bac1ab3	gitignore: ignore *.d files ... Makefile in trezor/trezor-mcu uses dependency generation now, without ignoring these files, git marks the submodules as dirty.	2016-08-21 20:25:35 +01:00
Jochen Hoenicke	f4ed55377d	Moved get_ethereum_address from ecdsa to bip32 ... The new name of the function is `hdnode_get_ethereum_address` and it gets a hdnode as input as opposed to a public key. This also avoids first computing the compressed public key and then uncompressing it. Test cases were adapted to work with new function. The test-vectors are the same as for bip32 and independently checked with an adhoc python implementation.	2016-08-18 16:21:33 +02:00

Jochen Hoenicke	9101c050aa	Smoother progress bar for wakeup ... Call interrupt twice as often; makes progress bar smoother.	2016-07-13 22:17:49 +02:00
Jochen Hoenicke	32bda8d1d9	Faster PBKDF2 by reusing intermediate results. ... The old implementation needed 6 sha transformations per iterations: - 2 for computing sha512 of seed, - 2 for computing digests of ipads/opads, - 2 for computing digests of intermediate hashes. The first 4 transformations are the same in every iteration so we cache them. A new function hmac_sha512_prepare computes these digests. We made sha512_Transform visible in pbkdf2 and prevent unneccessary big/little endian conversions back and forth.	2016-07-13 22:17:23 +02:00

Jochen Hoenicke	3390fcf89e	Compute pubkey only on demand. ... Remove fingerprint from hdnode structure (if you need it, call hdnode_fingerprint on the parent hdnode). Only compute public_key, when hdnode_fill_public_key is called.	2016-06-27 10:13:10 +02:00
