A hash is a fixed-size string generated from input data. It's unique to that data - even a small change produces a completely different hash.

Which algorithm should I use?

SHA-256 is recommended for most uses. MD5 and SHA-1 are faster but not secure for cryptographic purposes. SHA-512 is strongest but slower.

Can I verify file integrity?

Yes! Generate a hash of a downloaded file and compare it to the official hash to verify the file wasn't corrupted or tampered with.

MD5: 128-bit hash (fast, not secure for crypto)
SHA-1: 160-bit hash (deprecated for security)
SHA-256: 256-bit hash (recommended)
SHA-384/512: stronger variants of SHA-2

About Hash Generator

Hashes are the fingerprints of data — used to verify a download wasn't tampered with, check that two files are identical, or store data safely. This free tool generates MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes from any text or file instantly. It all runs in your browser, so whatever you hash is never uploaded to a server.

How to use Hash Generator

1
Enter text or upload file
Type or paste text, or upload a file you want to hash.
2
Select hash algorithm
Choose from MD5, SHA-1, SHA-256, SHA-512, or other hash algorithms.
3
Copy hash value
Copy the generated hash value to clipboard.
