Jochen Hoenicke	aa16b53bba	Refactored duplicated code (#84) ... Changed signature of public_ckd_address_optimized to not include the compressed public_key (uncompressed is in pub).	7 years ago

Pavol Rusnak	b55473a01e	add fingerprint output parameter to hdnode_private_ckd_cached function	8 years ago
Jochen Hoenicke	e855c60529	Use bn_add instead of bn_addmod (#80) ... The bip32 private key derivation used bn_addmod to handle wrap around. This was never sufficient as bn_addmod uses only bn_fast_mod, so an additional bn_mod is necessary. The bn_fast_mod helped when bn_mod was not side-channel safe. Now that bn_mod uses constant time code, we can get rid of the unnecessary bn_fast_mod step and use bn_add instead of bn_addmod.	8 years ago

Pavol Rusnak	d10ec230c0	add support for multibyte address versions	8 years ago
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.	8 years ago
Jan Pochyla	00413c0b6e	bip32: serialization returns nu. of written bytes	8 years ago
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.	8 years ago
Pavol Rusnak	b5f89bb478	fpr -> fingerprint	8 years ago
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.	8 years ago

Jochen Hoenicke	698f40f385	BIP-32 without gaps, prepare non-ecdsa curves ... * Split ecdsa_curve into curve_info and ecdsa_curve to support bip32 on curves that don't have a ecdsa_curve. * Don't fail in key derivation but retry with a new hash. * Adapted test case accordingly	8 years ago
Jochen Hoenicke	f8ac99ebb7	Check for error from get_curve_by_name.	8 years ago
Jochen Hoenicke	0bc1b70c4a	Use different seed modifier for different curves	8 years ago
Jochen Hoenicke	c983afd72f	Added curve type to HDNode ... Every curve gets it's own hierarchy and the curve is remembered in HD node. Fixed the private/public key derivations to use the right modulus.	8 years ago
Jochen Hoenicke	f93b003cbc	Extended comments, new function bn_add, a bug fix. ... Describe normalized, partly reduced and reduced numbers. Comment which function expects which kind of input. Removed unused bn_bitlen. Add bn_add that does not reduce. Bug fix in ecdsa_validate_pubkey: bn_mod before bn_is_equal. Bug fix in hdnode_private_ckd: bn_mod after bn_addmod.	9 years ago
Roman Zeyde	7c58fc11a4	Add support for NIST256P1 elliptic curve ... This enables SSH ECDSA public key authentication.	9 years ago
Pavol Rusnak	21d0bb437a	cleanup coding style	9 years ago
netanelkl	70dc71c87e	Some more stack memory wipe before leaving functions. ... Note that I preferred to change the multiple returns to multiple checks of a boolean to concentrate the erase into the last part of the functions.	9 years ago
netanelkl	aeefea054a	Added some private key nullification so that they won't be uncontrolled in the stack	9 years ago
