| description | A CLI utility for generating and verifying cryptographic file checksums (MD5, SHA1, SHA256). Supports recursive directory hashing and verification from file. |
Checksum Utility
A dedicated CLI tool for ensuring file integrity. Use this skill to verify downloads, check for changes in files, or generate checksums for release artifacts.
Features
- Multi-Algorithm: Supports
md5 (default), sha1, sha256, sha512.
- Recursive Hashing: Generates checksums for entire directories.
- Verification: (Planned) Validate files against a checksum list.
- JSON Output: Machine-readable output for integration scripts.
Usage
Calculate File Checksum
node skills/checksum/index.js --file <path> [--algo <md5|sha1|sha256>]
Example:
node skills/checksum/index.js --file package.json --algo sha256
Recursive Directory Checksum
node skills/checksum/index.js --dir <path> [--algo <md5|sha1|sha256>] [--json]
Example:
node skills/checksum/index.js --dir src/ --algo sha1 --json > checksums.json
Why use this instead of md5sum?
- Cross-Platform: Works on any OS with Node.js (Linux, macOS, Windows).
- No System Deps: Doesn't rely on
coreutils being installed.
- JSON Support: Easy to parse in other scripts.
