Skip Ratchet
This library implements the [Skip Ratchet paper][paper]. Skip ratchet is a data structure for deriving keys that maintain backward secrecy. Unlike hash chains, this data structure is capable of efficiently making large leaps in hash count.

## Usage
#### Creating a new ratchet and advancing it.
```rust
use skip_ratchet::Ratchet;
let mut ratchet = Ratchet::new();
ratchet.inc_by(10);
println!("{:?}", ratchet.derive_key());
```
#### Getting the previous versions of a ratchet.
```rust
use skip_ratchet::Ratchet;
let mut old_ratchet = Ratchet::new();
old_ratchet.inc_by(5);
let mut recent_ratchet = old_ratchet.clone();
recent_ratchet.inc_by(10);
for revision in recent_ratchet.previous(&old_ratchet, 10).unwrap() {
println!("{:#?}", revision);
}
```
## Building the Project

cd rs-skip-ratchet
```
- Build the project
```bash
cargo build
```
## Testing the Project
- Run tests
```bash
cargo test

## Contributing
### Pre-commit Hook
This library recommends using [pre-commit][pre-commit] for running pre-commit hooks. Please run this before every commit and/or push.
- Once installed, Run `pre-commit install` to setup the pre-commit hooks locally. This will reduce failed CI builds.
- If you are doing interim commits locally, and for some reason if you _don't_ want pre-commit hooks to fire, you can run
`git commit -a -m "Your message here" --no-verify`.
### Conventional Commits
This project *lightly* follows the [Conventional Commits convention][commit-spec-site]
to help explain commit history and tie in with our release process. The full
specification can be found [here][commit-spec]. We recommend prefixing your
commits with a type of `fix`, `feat`, `docs`, `ci`, `refactor`, etc...,
structured like so:
```
[optional scope]:
[optional body]
[optional footer(s)]
```
