## Historique du projet et usages

SHA-2 is Aaron D. Gifford's BSD-licensed C implementation of the SHA-224, SHA-256, SHA-384, and SHA-512 secure hash algorithms, accompanied by a small `sha2` command-line program.

### Historique du projet

Gifford dates the original implementation to a weekend in autumn 2000, specifically 14 October, when the SHA-256, SHA-384, and SHA-512 algorithms were newly described. The author distributes the implementation from his own cryptographic-hashing pages as source archives rather than through a public source-control forge.

### Historique d'adoption

The supplied package metadata records packages in Homebrew and DNF-based distributions. Its adoption is therefore best understood as a compact reference implementation and hashing utility preserved by package collections rather than a broad end-user application.

### Modes d'utilisation

The `sha2` executable computes SHA-2 message digests for files or input, while the C sources can also be embedded by developers who need the covered hash functions. It requires no persistent configuration or credentials.

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

The package captures an early open-source implementation of the SHA-2 family close to the algorithms' introduction. It remains interesting as small, auditable C code and as a historical alternative to the hashing commands bundled with larger cryptographic toolkits.

### Chronologie

- 2000: Aaron D. Gifford implemented the newly described SHA-256, SHA-384, and SHA-512 algorithms in C.
- Later: SHA-224 and SHA-1 support appeared on the author's consolidated BSD-licensed implementation page.

### Related projects

- The author's cryptographic code collection also includes SHA-1 and HMAC-SHA1 implementations; modern general-purpose toolkits provide overlapping digest commands and libraries.
