Compute cryptographic hashes of any text or file to verify downloads, compare data or generate checksums. All hashing is done in your browser.
How to use the Hash Generator
- Type text or choose a file.
- Hashes for all algorithms appear instantly.
- Paste an expected hash to verify a match.
Which hash should I use?
SHA-256 is the modern default for checksums and integrity. MD5 and SHA-1 are broken for security purposes but still used for legacy checksums. For passwords, use a slow algorithm like bcrypt or Argon2 instead of a plain hash.
Frequently asked questions
Can a hash be reversed?
No. Hash functions are one-way; you can only check whether an input produces the same hash.
Are my files uploaded?
No. Files are read and hashed locally.
