Why this tool exists
Hash Algorithm Explorer centralizes digest generation for incidents, releases, and compliance reviews. Hash everything once and share consistent checksums across teams.
Deployment verification
Generate SHA and CRC batches to confirm download integrity during rollouts.
Incident response
Compare suspect payloads against known-good digests while keeping a historical log.
Compliance reviews
Share prescriptive digest sets (SHA-2, SHA-3, legacy MDx) for auditors and security teams.
Quick start
Paste a payload once, select algorithms or presets, and copy digests or compare against a known signature.
- Open the Hash Algorithm Explorer, drop the payload to hash, and decide whether you need digest comparison or just multi-hash output.
- Select algorithms manually or apply a preset (modern, legacy, checksum, performance). The selection counter keeps you under the 40-algorithm limit.
- Submit the form to render the digest cards, copy the ones you need, or paste a digest into Compare mode to highlight matches.
Supported inputs
- Accepts plain text, JSON, or log snippets—binary-safe thanks to server-side hashing.
- Handles multi-line payloads without changing whitespace.
- Compare digest accepts any lowercase or uppercase digest (with or without spaces).
Mode 01
Compare digest walkthrough
- Paste a reference digest into the Compare field to highlight any algorithms producing the same value.
- The summary bar shows match, mismatch, and pending counts so you can spot parity at a glance.
- Difference chips display how many characters diverge so near-miss digests stand out.
Mode 02
Presets & groups
Use curated packs (modern, legacy, checksums, performance) or mix individual algorithms with full descriptions.
- Presets load curated algorithms instantly (e.g., SHA-2 core, SHA-3 + Blake, legacy MD5/SHA-1/CRC).
- Algorithm groups include helper descriptions explaining when to use Whirlpool, RIPEMD, Murmur, and others.
- Manual selection updates the preset badge to “Custom” so you always know what is currently active.
Outputs & snippets
Every algorithm produces its own digest card with copy helpers, bit lengths, and descriptions for onboarding new teammates.
- Each digest card shows the algorithm label, output length, bit strength, and description.
- Copy buttons sit beside every digest with visual confirmation so batching hashes is easy.
- Matching digests receive a success badge while mismatches show subtle warnings—perfect for handoff screenshots.
Field notes
Keep hashing workflows predictable with these quick wins.
- Load the Performance preset when you only need XXHash, Murmur, or FNV speed for non-cryptographic use cases.
- Use Compare mode when validating vendor checksums; paste their value once and scan the highlighted matches.
- Keep legacy digests (MD5/SHA-1) enabled alongside SHA-2 when you must support older systems.
- Pair this tool with the UUID + Hash Lab when you need both batch UUIDs and multi-algorithm signatures.
