history
Project history and usage
sss-cli is a small Rust command-line wrapper around David Sprenkels's SSS library. Its two executables split a secret into Shamir shares and recombine a threshold number of shares.
Project history
The official GitHub repository was created in 2017. The project packages the author's secure Shamir secret-sharing implementation as the `secret-share-split` and `secret-share-combine` commands.
The 0.1.2 change documented in the README moved the cryptographic wrapper to RustCrypto's `crypto-secretbox` crate. The tool adds authenticated encryption so tampered shares are detected when a secret is reconstructed.
Adoption history
Upstream originally documented installation from a Git branch with Cargo and from a third-party Homebrew tap. The supplied package metadata records later availability in Homebrew and Nix, giving the focused Rust utility conventional Unix package-manager distribution.
How it is used
Users pipe a secret into `secret-share-split`, select the number of shares and reconstruction threshold, store each output line separately, and later pipe enough shares into `secret-share-combine`. The commands are stream-oriented and therefore fit shell pipelines without a project configuration file.
Why package nerds care
sss-cli is a compact example of packaging a cryptographic primitive as composable Unix filters. It is notable for exposing secret splitting without a service, account, or credentials store and for distributing the same Rust code through Cargo and system package managers.
Timeline
- 2017: The official sss-cli GitHub repository was created.
- 2020s: The project became available through Homebrew and Nix in addition to Cargo-based installation.
Related projects
- The upstream `dsprenkels/sss` library supplies the Shamir secret-sharing implementation wrapped by sss-cli; RustCrypto's `crypto-secretbox` supplies the authenticated-encryption primitive noted in the changelog.
