## ecgen

Tool for generating Elliptic curve domain parameters.

### Usage

#### ecgen
The main binary of the tool, does the hard work.
```
ecgen --fp/--f2m -r BITS
```
 - `--fp`/`--f2m` specifies the field type(prime/binary).
 - `-r` requests a random curve to be generated, currently only supported feature.
 - `-o/--output FILE` writes output to `FILE`.
 - `-i/--input FILE` reads input from `FILE`.
 - `-a/--append` appends to output file(doesn't overwrite it).
 - `-d/--datadir DIR` specifies the PARI/GP datadir containing the `seadata` and `elldata` packages.

### Build
```
git clone https://github.com/J08nY/ecgen.git
cd ecgen
make
```

### Requirements
ecgen uses the [PARI/GP](http://pari.math.u-bordeaux.fr/) library for elliptic
curve arithmetic and it's SEA point counting algorithm implementation.
