Optimized C library for EC operations on curve secp256k1
This library is a work in progress and is being used to research best practices. Use at your own risk.
Features:
- secp256k1 ECDSA signing/verification and key generation.
- Adding/multiplying private/public keys.
- Serialization/parsing of private keys, public keys, signatures.
- Constant time, constant memory access signing and pubkey generation.
- Derandomized DSA (via RFC6979 or with a caller provided function.)
- Very efficient implementation.
- Developed at network:cryptocurrencies
- Sources inherited from project openSUSE:Factory

- Update to 0.5.0:
Added:
* New function secp256k1_ec_pubkey_sort that sorts public keys
using lexicographic (of compressed serialization) order.
Changed:
* The implementation of the point multiplication algorithm used
for signing and public key generation was changed, resulting
in improved performance for those operations. The related
configure option --ecmult-gen-precision was replaced with
--ecmult-gen-kb (ECMULT_GEN_KB for CMake).
This changes the supported precomputed table sizes for these
operations. The new supported sizes are 2 KiB, 22 KiB, or 86
KiB (while the old supported sizes were 32 KiB, 64 KiB, or 512 KiB).
ABI Compatibility:
* The ABI is backward compatible with versions 0.4.x and 0.3.x.
