Check MD5 files in your browser
The list of MD5 hashes that comes with downloads, backups and disc images. Drop it with its files right here to see they're whole. Nothing leaves your device.
Or drop it anywhere on this page
What you'll see
Your list opens with each file it names checked against the files dropped with it.
- CRC32, MD5, SHA-1, SHA-256 and SHA-512
- Matches, doesn't match, or not dropped
- Worked out on your device • Nothing uploaded
- Every name and hash, and the comments
About MD5
Download sites, backup tools and archives put an .md5 file beside the files they share, so you can tell that what you got is what they sent. md5sum, from GNU's coreutils, writes them, and Windows' certutil and the Mac's md5 work out the same hashes.
An MD5 file is text: a line for each file with its MD5 in 32 hex digits and its name, an asterisk before the name when it was read as binary, or BSD's form, MD5 (name) = hash. Some hold a lone hash, for the file they're named after. sha1sum, sha256sum and sha512sum write the same lines with longer hashes.
Filepeek works out the MD5 of each file dropped with the list, on your device, and marks each one: it matches, it doesn't, or it wasn't dropped. SHA-1, SHA-256 and SHA-512 lists, .sha1, .sha256 and .sha512, open the same way.

Questions
How do I check an MD5 file?
Drop the .md5 together with the files it names, or choose Peek an MD5 and pick them all. Each file's MD5 is worked out and compared, and the card says which match.
Does it check SHA-256 files too?
Yes. .sha256, .sha1 and .sha512 lists open the same way, in GNU's form or BSD's.
What if my .md5 holds only a hash?
Then it's for the file it's named after, like ubuntu.iso.md5 for ubuntu.iso. Drop the two together.
Is an MD5 enough to trust a download?
It catches damage on the way. Someone can make two files with the same MD5 on purpose, so for software from a stranger, check the SHA-256 the maker's own site gives.
What's a .tar.md5 file?
Samsung's firmware: a TAR of its images with its own MD5 at the end, which Odin checks before it flashes. It opens here as its images, and Verify checks that MD5.
