Open source & community

Open source & community contributions

Software I publish so other developers can use, inspect and improve it. Each entry says what it is for, how to start, where to report problems and what it does not do. Public source and an open-source licence are not the same thing; the licence is stated for each.

SigSieve

MIT

Forwards selected identities from an existing SSH agent, with optional destination binding. Alpha.4 has macOS arm64 and Linux x86_64 downloads with checksums and provenance; the macOS Homebrew tap builds from source. No account or telemetry.

Limits
Experimental alpha.4, not independently audited. Homebrew tested on Apple Silicon only. Secretive/Touch ID behavior has not been reverified for alpha.4; an allowed key can still be misused while forwarding is active.
