Pavol Rusnak	d61a151900	add bn_divmod1000 including unit test	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
Jochen Hoenicke	f2081d88d8	New jacobian_add that handles doubling. ... Fix bug where jacobian_add is called with two identical points.	9 years ago
Jochen Hoenicke	6ba4d288b0	Cleaned up bignum code ... 1. Fixed bn_multiply_step to handle small primes. 2. Removed many calls to bn_mod to prevent side-channel leakage.	9 years ago
Roman Zeyde	7c58fc11a4	Add support for NIST256P1 elliptic curve ... This enables SSH ECDSA public key authentication.	9 years ago
Jochen Hoenicke	56f5777b68	Refactored code for point doubling. ... New function `bn_mult_3_2` that multiplies by 3/2. This function is used in point_double and point_jacobian_double. Cleaned up point_add and point_double, more comments.	9 years ago
Jochen Hoenicke	d4788bddfd	Added modulus to bn_subtractmod	9 years ago
