# Roughenough
**Roughenough** is a **WORK IN PROGRESS** Rust implementation of the [Roughtime](https://roughtime.googlesource.com/roughtime) 
secure time synchronization protocol.

## About the Roughtime Protocol
[Roughtime](https://roughtime.googlesource.com/roughtime) is a protocol that aims to achieve rough 
time synchronisation in a secure way that doesn't depend on any particular time server, and in such
a way that, if a time server does misbehave, clients end up with cryptographic proof of it. It was 
created by Adam Langley and Robert Obryk.
