Hash algorithms, checksums, and file integrity
Hash functions turn text or file content into repeatable fixed-length digests for comparison, checksums, and integrity checks.
Hash output lengths
- MD5 produces a 32-character hexadecimal digest.
- SHA-1 produces a 40-character hexadecimal digest.
- SHA-256 produces a 64-character hexadecimal digest.
- SHA-384 produces a 96-character hexadecimal digest.
- SHA-512 produces a 128-character hexadecimal digest.
Text and file checks
A small change in text or file content should produce a very different hash. That makes hashes useful for comparing whether two inputs are exactly the same.
Security-sensitive use
MD5 and SHA-1 are useful for older compatibility checks, but they should not be chosen for new security-sensitive workflows. Prefer SHA-256 or stronger algorithms when the hash matters for integrity.
Common workflows
- Compare a downloaded file to a published checksum.
- Check whether two text blocks or files are identical.
- Generate cache keys for non-secret content.
- Create repeatable digests for development and testing workflows.

SHA-256 Generator
Generate a SHA-256 hash from text or file input for modern integrity checks, checksums, and developer workflows.
SHA-1 Generator
Generate a SHA-1 hash for legacy compatibility checks, old checksum workflows, and historical digest comparisons.
SHA-512 Generator
Generate a SHA-512 hash from text or file input for long digest output and high-strength integrity checks.
MD5 Hash Generator
Generate an MD5 hash for legacy checksums, older compatibility workflows, and non-security file or text comparisons.
File Hash Generator
Generate a local file hash in the browser to compare downloads, archives, images, documents, and other files against published checksums.
Checksum Generator
Generate a checksum for text or file input and compare it against a published digest to check whether the content changed.
Hash generator notes
Hashes are useful for checksums, integrity checks, cache keys, and comparing files or text. MD5 and SHA-1 are included for compatibility checks, but modern security-sensitive workflows should prefer SHA-256 or stronger algorithms.
Frequently asked questions
What hash algorithms are supported?
The generator supports MD5, SHA-1, SHA-256, SHA-384, and SHA-512 for text and local file inputs.
Are files uploaded to generate hashes?
No. File hashes are calculated locally in your browser, so the selected file is not uploaded to PlanetToolbox.
Should I use MD5 or SHA-1 for security?
No. MD5 and SHA-1 are included for compatibility checks. For modern integrity checks, prefer SHA-256 or stronger algorithms.
What are hashes used for?
Hashes are commonly used for file integrity checks, checksums, cache keys, data comparison, and verifying that text or files have not changed.
