secrecy.rs 🤐

A simple secret-keeping library for Rust.

About

secrecy is a simple, safe (i.e. forbid(unsafe_code) library which provides wrapper types and traits for secret management in Rust, namely the Secret<T> type for wrapping another value in a "secret cell" which attempts to limit exposure (only available through a special ExposeSecret trait).

This helps to ensure secrets aren't accidentally copied, logged, or otherwise exposed (as much as possible), and also ensures secrets are securely wiped from memory when dropped.

Minimum Supported Rust Version

Rust 1.60 or newer.

In the future, we reserve the right to change MSRV (i.e. MSRV is out-of-scope for this crate's SemVer guarantees), however when we do it will be accompanied by a minor version bump.

serde support

Optional serde support for parsing owned secret values is available, gated under the serde cargo feature.

It uses the Deserialize and DeserializeOwned traits to implement deserializing secret types which also impl these traits.

This doesn't guarantee serde (or code providing input to serde) won't accidentally make additional copies of the secret, but does the best it can with what it is given and tries to minimize risk of exposure as much as possible.
