Hash Generator
5 toolsGenerate MD5, SHA-1, SHA-256, and SHA-512 hashes.
Runs in your browser — your files and text stay on your device
Generate MD5, SHA-1, SHA-256 and other hashes of text. Hashes are one-way fingerprints, useful for checksums and comparing data. MD5 and SHA-1 are not safe for security; use SHA-256 or better, and never use a plain hash to store passwords. Hashing happens in your browser.
How to use this tool
- 1Type or paste text.
- 2MD5, SHA-1/256/512, SHA3-256, and CRC32 compute automatically.
- 3Click any hash to copy it.
Frequently asked questions
Which hash algorithm should I use?
SHA-256 is the current standard for checksums. MD5/SHA-1 are broken for security use but fine for detecting accidental corruption. CRC32 is fast but only for basic integrity checks.
Can I reverse a hash?
No — hashing is one-way by design.
Is my text sent anywhere?
No — everything runs locally, using the Web Crypto API where possible.
