## ⚠️ Security Warning
This crate is provided for the purposes of legacy interoperability with
protocols and systems which mandate the use of MD5.
However, MD5 is [cryptographically broken and unsuitable for further use][2].
Collision attacks against MD5 are both practical and trivial, and
[theoretical attacks against MD5's preimage resistance have been found][3].
[RFC6151][4] advises no new IETF protocols can be designed MD5-based constructions,
including HMAC-MD5.

Minimum supported Rust version can be changed in the future, but it will be
