## ⚠️ Security Warning: [Hazmat!][hazmat-link]
|
||
|
|
|
||
|
|
This crate does not ensure ciphertexts are authentic (i.e. by using a MAC to
|
||
|
|
verify ciphertext integrity), which can lead to serious vulnerabilities
|
||
|
|
if used incorrectly!
|
||
|
|
|
||
|
|
No security audits of this crate have ever been performed, and it has not been
|
||
|
|
thoroughly assessed to ensure its operation is constant-time on common CPU
|
||
|
|
architectures.
|
||
|
|
|
||
|
|
USE AT YOUR OWN RISK!
|
||
|
|
|
||
|
|
## Minimum Supported Rust Version
|
||
|
|
|
||
|
|
Rust **1.56** or higher.
|
||
|
|
|
||
|
|
Minimum supported Rust version can be changed in the future, but it will be
|
||
|
|
done with a minor version bump.
