How to generate a hash
- Enter text in the input field — hashes update as you type.
- Or upload a file to compute its checksum hash.
- Copy any hash — MD5, SHA-1, SHA-256, or SHA-512 — with one click.
- Use the compare tool to verify if two hashes match.
Hash algorithm comparison
- MD5 — 32 characters, fast but not cryptographically secure. Good for checksums.
- SHA-1 — 40 characters, deprecated for security but still used in Git.
- SHA-256 — 64 characters, secure and widely used. Recommended for most applications.
- SHA-512 — 128 characters, highest security. Used in certificate signing and critical systems.
