|
## ⚠️ 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
|
|
|
|
Rust **1.41** or higher.
|
|
|
|
Minimum supported Rust version can be changed in the future, but it will be
|
|
done with a minor version bump.
|
|
|
|
## SemVer Policy

|
|
|
- All on-by-default features of this library are covered by SemVer
|
|
- MSRV is considered exempt from SemVer as noted above
