f2081d88d8 New jacobian_add that handles doubling. 
Fix bug where jacobian_add is called with two identical points.

60e36dac3b Fixed conditional_negate for larger numbers 
Without the bn_mod the numbers get larger (but still < 2*prime), so
conditional_negate should handle this.

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.

d2120d6da1 two bugfixes: 1. nist256p1.c was not included in setup.py, causing import errors when using TrezorCrypto.so in Python. 2. if you attempted a hardened derivation in python using the compiled TrezorCrypto module, an IntegerOverflowError would occur because Python ints are always signed. one-line fix by changing int to unsigned int in the pyx file 2015-07-06 12:43:30 -04:00

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.
