=======

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
```

doc: crypto/secp256k1 GMP dependency package name. Linux build documentation is mostly geared towards Ubuntu 14.04 (LTS). Appropriate package is called `libgmp-dev` there. Note that on pristine installations building `geth` with godep will fail because this header is missing. This is not documented in the top-level README, but is on the wiki: https://github.com/ethereum/go-ethereum/wiki/Installation-Instructions-for-Ubuntu#building-geth-command-line-client That page recommends `libgmp3-dev`, which ATM provides same version as `libgmp-dev`. 2015-04-23 17:33:48 +03:00
