GSSAPI, SPNEGO, PKINIT.\n\n**No C FFI. No system krb5. No libgssapi. Just `cargo add krb5-rs`.**\n\n## Features\n\n- **Kerberos V5 Client** — TGT acquisition, service ticket requests\n- **GSSAPI/SPNEGO** — HTTP Negotiate authentication\n- **PKINIT** — X.509 certificate-based authentication\n- **FAST** — Flexible Authentication via Secure Tunneling\n- **Credential Cache** — Read/write ccache and keytab formats\n\n## Why?\n\nMIT Kerberos and Heimdal are massive C codebases (~450K and ~620K SLOC respectively) with decades of CVEs. Every Rust project needing Kerberos auth depends on FFI bindings to these C libraries, inheriting their build complexity and security risks.\n\n`krb5-rs` is a ground-up Rust implementation using `rasn` (ASN.1) + RustCrypto. Pure Rust, single binary, cross-compiles to musl.\n\n## Status\n\n**Pre-release.** API is unstable. Not ready for production use.\n\n## RFCs\n\n| RFC | Description | Status |\n|-----|-------------|--------|\n| [RFC 4120](https://www.rfc-editor.org/rfc/rfc4120) | Kerberos V5 core | Planned |\n| [RFC 4121](https://www.rfc-editor.org/rfc/rfc4121) | GSSAPI mechanism | Planned |\n| [RFC 3961](https://www.rfc-editor.org/rfc/rfc3961) | Encryption specs | Planned |\n| [RFC 4556](https://www.rfc-editor.org/rfc/rfc4556) | PKINIT | Planned |\n| [RFC 6113](https://www.rfc-editor.org/rfc/rfc6113) | FAST | Planned |\n\n## License\n\nApache-2.0\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fstructured-world%2Fkrb5-rs","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fstructured-world%2Fkrb5-rs","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fstructured-world%2Fkrb5-rs/lists"}
