Gregory Maxwell	71712b27e5	Switch to C89 comments in prep for making the whole codebase C89 compatible. ... This should be whitespace/comment only changes and should produce the same object code.	2014-11-15 07:33:07 -08:00
Gregory Maxwell	65a14abb48	Fix varrious signed/unsigned comparisons.	2014-11-12 15:47:12 -08:00

Pieter Wuille	1136bedbc2	Make secp256k1_ge_set_gej work with the point at infinity	2014-09-13 00:46:32 +02:00
Gregory Maxwell	2f6c801911	Try to not leave secret data on the stack or heap. ... This makes a basic effort and has not been audited. Doesn't appear to have a measurable performance impact on bench. It also adds a secp256k1_num_free to secp256k1_ecdsa_pubkey_create.	2014-08-14 07:06:36 -07:00
Peter Dettman	f16be77ffc	Use batch inversion in G precomputation	2014-07-17 15:33:00 +07:00

Peter Dettman	09ca4f32e2	secp256k1_fe_sqrt checks for success ... - secp256k1_fe_sqrt now checks that the value it calculated is actually a square root. - Add return values to secp256k1_fe_sqrt and secp256k1_ge_set_xo. - Callers of secp256k1_ge_set_xo can use return value instead of explicit validity checks - Add random value tests for secp256k1_fe_sqrt	2014-05-21 10:22:14 +07:00
