=======
golang secp256k1 library
Implements cryptographic operations for the secp256k1 ECDSA curve used by Bitcoin.
Installing
===
GMP library headers are required to build. On Debian-based systems, the package is called `libgmp-dev`.
```
sudo apt-get install libgmp-dev
```
Now compiles with cgo!
Test
===
To run tests do
```
go tests
