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.

I installed this binary package (both .so and .a) but it won't work with .go code. The original C code won't compile with my FreeBSD system. Any idea how to fix this?

Compiling the original C source code (tar.gz) returned the following error.

Thanks for your report. Sorry for the long silence - I was on vacation. I will look into this this week.

Any update?

It builds fine on my system. Please make sure to strictly follow the instructions when building this package. Using the tar.gz won't work.
