# Notice

The Notary project has officially been accepted in to the Cloud Native Computing Foundation (CNCF).
It has moved to https://github.com/theupdateframework/notary. Any downstream consumers should update
their Go imports to use this new location, which will be the canonical location going forward.

We have moved the repo in GitHub, which will allow existing importers to continue using the old
location via GitHub's redirect.
This repository provides an implementation of
*[The Update Framework specification](https://github.com/theupdateframework/specification)*
and all references to `notary` in this repository refer to the implementation of the client
and server aligning with the [TUF](https://github.com/theupdateframework/specification) specification.

The most prominent use of this implementation is in Docker Content Trust (DCT).
The first release [v0.1](https://github.com/notaryproject/notary/releases/tag/v0.1) was released in November, 2015.

The aim is to make the internet more secure by making it easy for people to
publish and verify content. We often rely on TLS to secure our communications
with a web server, which is inherently flawed, as any compromise of the server
enables malicious content to be substituted for the legitimate content.

The `notary` client and server is based on [The Update Framework](https://www.theupdateframework.com/), a secure general design for the problem of software distribution and updates. By using TUF, the `notary` client and server achieves a number of key advantages:

* **Survivable Key Compromise**: Content publishers must manage keys in order to sign their content. Signing keys may be compromised or lost so systems must be designed in order to be flexible and recoverable in the case of key compromise. TUF's notion of key roles is utilized to separate responsibilities across a hierarchy of keys such that loss of any particular key (except the root role) by itself is not fatal to the security of the system.
* **Freshness Guarantees**: Replay attacks are a common problem in designing secure systems, where previously valid payloads are replayed to trick another system. The same problem exists in the software update systems, where old signed can be presented as the most recent. Notary makes use of timestamping on publishing so that consumers can know that they are receiving the most up to date content. This is particularly important when dealing with software update where old vulnerable versions could be used to attack users.

# Getting started with the Notary CLI
# Getting started with the notary CLI

Get the Notary Client CLI binary from [the official releases page](https://github.com/theupdateframework/notary/releases) or you can [build one yourself](#building-notary).
The version of the Notary server and signer should be greater than or equal to Notary CLI's version to ensure feature compatibility (ex: CLI version 0.2, server/signer version >= 0.2), and all official releases are associated with GitHub tags.
