rsasl is an framework for RFC 4422; the Simple Authentication and Security Layer - aka SASL.
It is designed to enable implementing SASL support in protocol handling crates while abstracting away the details, allowing downstream users to select available mechanisms and add support for additional mechanisms without any changes required in the protocol handling crate.
rsasl provide a number of mechanisms by itself:
- ANONYMOUS
- EXTERNAL
- GSSAPI
- LOGIN
- OAUTHBEARER
- PLAIN
- SCRAM-SHA-1 and SCRAM-SHA-1-PLUS
- SCRAM-SHA-256 and SCRAM-SHA-256-PLUS
- SCRAM-SHA-512 and SCRAM-SHA-512-PLUS
- XOAUTH2
Support for the following mechanisms was available in rsasl 1 but is not yet implemented in rsasl 2:
- OPENID20
- SAML20
- GS2-KRB5
- KERBEROS_V5
- NTLM
- SECURID
- CRAM-MD5
- DIGEST-MD5
Additional mechanisms can be implemented by other crates. (NOTE: In the current v2.0.0
this feature is unstable)
rsasl allows users to select the available mechanisms at compile time using cargo features.
For an overview refer to the module documentation of rsasl::mechanisms
.
The current msrv rsasl is Rust 0
, however do note that certain features (e.g. registry_static
) have
dependencies with much more recent msrv.
The CHANGELOG.md contains a detailed release history, including added features and fixed bugs.
Major version 1 of this crate uses gsasl-sys which are binding
to GNU gsasl. This makes the use of unsafe
code and FFI necessary.
You can find the latest 1.X.Y version in the branch 1.X.X
Version 2.0.0
is a pure-Rust rewrite of this crate that is able to drop almost all unsafe
code from the crate.
The main
branch contains the tagged stable releases, the current state of development can be found in the development
state.
Version 2 and later of this library are dual licensed under both Apache-2.0 and MIT, at your option.
You can find a few examples on GitHub.
