sha2-tool

Minimal command-line hashing utility for EriX SHA-2 workflows.

This tool is intended as a clean-room sha256sum/sha512sum style utility, built on lib-sha2.

Scope

Implemented commands:

  • hash files and stdin with SHA-512
  • hash files and stdin with SHA-256
  • print deterministic lowercase hex digests

This tool does not provide:

  • HMAC/KDF functionality
  • signature verification
  • recursive directory hashing policy

Why this exists

EriX needs a local, auditable hashing CLI for development pipelines and test fixtures without external dependencies.

Design constraints

  • no external Rust crates
  • deterministic output formatting
  • explicit, non-ambiguous error messages
  • suitable for CI and scripting

Planned usage shape

Examples:

  • sha2-tool sha512 <file>
  • sha2-tool sha256 <file>
  • sha2-tool sha512 - (read stdin)

Dependencies

  • lib-sha2 for hashing implementation

Status

Implemented baseline.

sha256 and sha512 command paths, stdin mode, and sum-style output are implemented. Remaining work focuses on robustness tests and optional compatibility flags.

See ARCHITECTURE.md and ROADMAP.md.
