Hash Generator

About the Hash Generator

The Hash Generator helps developers, security professionals, and IT teams compute cryptographic checksums for text snippets and files. Pick an algorithm (MD5, SHA-1, SHA-256, SHA-512, and more), paste in text or drop a file, and get the hex digest in seconds.

Everything runs locally in your browser using the Web Crypto API — your text and files never leave your device — so you can hash sensitive content without uploading it anywhere.

What you can control

• Algorithm selection: MD5, SHA-1, SHA-256, SHA-384, SHA-512
• Text input or file input (any size your browser can hold)
• Bulk mode — one input per line for batch hashing
• Output format: hex digest, with one-click copy to clipboard
• Side-by-side comparison to verify a hash matches an expected value

Common uses

• Verifying file downloads against a published checksum
• Confirming two files are byte-identical without uploading them
• Generating deterministic IDs from input strings
• Spot-checking integrity after a file transfer or deploy

Tips

• Prefer SHA-256 or stronger — MD5 and SHA-1 are not safe for security-critical use
• Identical inputs always produce identical hashes — useful for deduplication
• Whitespace and line endings count — they change the hash
• For password storage, use a dedicated KDF (bcrypt, argon2), not a plain hash

If you're verifying a download, paste the publisher's checksum into the comparison field — the tool highlights a match or mismatch instantly, so you don't need to eyeball long hex strings.
