How to use
When it helps
Download pages for installers and operating system images often list a SHA-256 or MD5 checksum. Compute the same value from the file you downloaded and compare: if they match, the file was not corrupted in transit or swapped along the way.
This tool reads files in chunks so even multi-gigabyte files can be hashed in the browser. The SHA family uses the browser's built-in crypto, MD5 uses its own implementation, and all five results appear in one table. Paste the official value and it finds the matching algorithm and shows whether it matches.
Identical content always gives the same hash, and changing a single character gives a completely different one. MD5 and SHA-1 have known collision attacks, though, so use SHA-256 or stronger for security checks.
FAQ
Which hash should I use?
Use whichever one the download page lists. If you get to choose, SHA-256 is a good default. MD5 and SHA-1 are fast but not recommended for security purposes.
Does it work with large files?
Yes, files are read in chunks. Because of how browsers handle SHA, though, the whole file is loaded into memory for those, so files over 1GB can be a strain on phones.
Same text, but a different value than another site.
A different line break or a trailing space changes the value. This tool hashes text as UTF-8, so sites using another character encoding can give different results.
Can I turn a hash back into the original?
No. Hashes only work in one direction. That is why they are used for passwords, though password storage should use a slow dedicated method such as bcrypt.
Are my files uploaded?
No. Everything is calculated on this device, and it keeps working even offline.
