README
akd 
An implementation of an auditable key directory (also known as a verifiable registry or authenticated dictionary).
Auditable key directories can be used to help provide key transparency for end-to-end encrypted messaging.
This implementation is based off of the protocols described in SEEMless, with ideas incorporated from Parakeet.
This library provides a stateless API for an auditable key directory, meaning that a consumer of this library must provide their own solution for the storage of the entries of the directory.
Documentation
The API can be found here along with an example for usage. To learn more about the technical details behind how the directory is constructed, see here.
Installation
Add the following line to the dependencies of your Cargo.toml:
akd = "0.12.0-pre.11"
Minimum Supported Rust Version
Rust 1.51 or higher.

akd |
✓ | Main implementation of AKD which a service provider that manages the underlying directory would need to run. A good starting point for diving into this implementation. |
akd_core |
✓ | Minimal library consisting of core operations in AKD. |

Audit
This library was audited by NCC Group in August of 2023. The audit was sponsored by Meta for its use in WhatsApp's key transparency deployment.
The audit found issues in release v0.9.0, and the fixes were subsequently incorporated into release v0.11.0. See the full audit report here.
