How to use the Hash Generator
- Type text, or drop a file, and all hashes are computed automatically.
- Paste an expected hash in the compare box to check whether it matches.
- Click any hash to copy it.
About this tool
A hash is a fixed-length fingerprint of data: change one byte and the hash changes completely. Hashes are used to verify downloads (compare the SHA-256 published by the site with the file you got), detect duplicate files and store passwords. SHA-256 and SHA-512 are computed with the browser’s Web Crypto API; MD5 is included for legacy checksums but is no longer considered secure against deliberate collisions.
Frequently asked questions
Is MD5 still safe?
For detecting accidental corruption, yes. For security purposes, no — collisions can be manufactured. Use SHA-256 or better.
Can I hash large files?
Yes. Files are read in your browser and hashed locally; multi-gigabyte files work but take a while.
Why does my hash differ from the one on the website?
Usually a different file (incomplete download or different version), or you hashed text with a trailing newline. Hashes are case-insensitive in hex, so A1 and a1 are the same.
