## Historique du projet et usages

ssss is a small Unix-oriented command-line implementation of Shamir's Secret Sharing Scheme. Its package-manager identity is unusually literal: it ships two commands, ssss-split and ssss-combine, for turning a secret into threshold shares and reconstructing it from enough shares.

### Historique du projet

The official project page says ssss was written in 2006 by B. Poettering, licensed under GPL v2, linked against GNU libgmp, and designed for UNIX/Linux machines using /dev/random as an entropy source. The homepage distributes release tarballs from 0.1 through 0.5 rather than pointing to a public source-control repository.

### Historique d'adoption

The project page notes a Debian package and Freshmeat announcements, reflecting the mid-2000s Unix packaging path for small security tools. The supplied package facts show it later remained available across Homebrew, Debian, Ubuntu, Fedora/DNF, Alpine, MacPorts, and Nix, which is the sort of long-tail packaging that keeps old but useful CLI cryptography tools reachable.

### Modes d'utilisation

Typical usage is interactive: ssss-split prompts for a secret and emits numbered shares for a threshold scheme, while ssss-combine reads enough shares to reconstruct the secret. The manpage also documents hex mode for binary material, quiet modes for scripts, and a hybrid pattern where large data is encrypted with tools such as OpenSSL or GPG and only the key is shared.

### Pourquoi les passionnés de paquets s'y intéressent

Package maintainers care about ssss because it is a compact, classic Unix security utility with stable command names and few moving parts. Its continued presence in multiple package managers makes it a reference point for threshold-secret workflows even when newer tools wrap Shamir sharing with additional authentication or modern cryptographic framing.

### Chronologie

- 2006: Official project page says ssss was written by B. Poettering.
- 2006: ssss 0.1 through 0.5 tarballs were published on the project homepage.
- 2018: Official homepage copyright and last-modified metadata show the page was still maintained.

### Related projects

- The homepage links ssss to the broader Shamir secret sharing tradition and mentions seccure as another cryptography project by the same author. Its usage notes also point to OpenSSL and GPG for encrypting larger payloads before splitting only the symmetric key.
