OxiSH: SSH server written in Rust

OxiSH is an SSH server written in Rust. It is a work in progress and not yet fit for usage.

Please don't publicize this project at its current stage. Funding to advance its development is welcome.

Intended features

• Improved security track record
• Limit features to the most common
• Efficient -- low latency
• Usable as server and library

Limitations

• Will only support modern clients
• May require a modern platform/Rust compiler (currently 1.75)
• No support for older cryptographic algorithms
