2015-10-02Testing shows that signature and verification are both faster withRob Austein
mixed Jacobian-affine addition, so go with that. Minor additional clean-up and comments.
2015-10-02Revise point addition and point scalar multiplication routines to useRob Austein
mixed Jacobian-affine coordinates, per a suggestion from Pavel. Old code still present under compile time conditional for easy comparison, but will probably go away soon along with a bit of minor cleanup.
2015-09-14Fencepost error in hal_ecdas_key_from_ecpoint().Rob Austein
2015-09-11Avoid gratuitous assertion failure if caller gives us a larger bufferRob Austein
than necessary when writing private key to DER.
2015-09-06Add ECPoint I/O functions. ASN.1 cleanup.Rob Austein
2015-09-02Add PKCS11 ECDSA signature format.Rob Austein
2015-09-02Clean up excessively complicated handling of opaque types in hash andRob Austein
RSA code; use simpler model (pointer to incomplete structure) used in ECDSA code. Refactor RSA code to use shared ASN.1 routines.
2015-08-27Add point validation check to hal_ecdsa_verify(). Update README.mdRob Austein
and code comments.
2015-08-26Signature works better if we read the entire hash.Rob Austein
2015-08-25More ASN.1 fixes.Rob Austein
2015-08-25Rework RFC 5915 ASN.1.Rob Austein
2015-08-25ASN.1 bugfixes.Rob Austein
2015-08-24First stumblings towards ECDSA test code.Rob Austein
2015-08-22Rework point_scalar_multiply() to avoid a timing leak with small scalars.Rob Austein
2015-08-22Add hal_ecdsa_verify(). Move hashing out of ECDSA routines. Clean upRob Austein
a few bits that didn't pass self-review.
2015-08-21Updated point doubling and addition to use algorithms from theRob Austein
hyperelliptic.org formula database. Compiles, still not tested.
2015-08-21Snapshot along the way to ECDSA. Code mostly written, except forRob Austein
ecdsa_verify(). Untested. Point addition and doubling algorithms are the ones from libtomcrypt, main point of this commit is to save those before replacing them with faster algorithms from hyperelliptic.org.
