How to check the md5 checksum of a file?

[DesertFox]

Hello,

What is the simplest way to check a md5 checksum of a file? Can it be done in the terminal or is there a nice little app out there somewhere?

Thanks in advance!

Terminal can do it with md5 fileName. You can also do a SHA1 checksum with sha1 fileName

I've always thought I had to download additional software for SHA1. And, indeed:

-bash: sha1: command not found

You need to use openssl md5 or openssl sha1, not just md5 or sha1. You don't need to download anything additional for it. 😉

"md5" works by itself, but it looks like it "openssl md5" and "openssl sha1" work too 🙂

Thanks guys. Problem Solved 🙂

This is how you verify MD5 checksums on Windows
The Easy Way (digestIT with GUI)

digestIT is a graphical tool that should be easier to use for most Windows users.
Download digestIT.
Navigate in Windows Explorer to the directory where you saved/downloaded the OpenOffice.org archive.
Right click the OpenOffice.org archive file in and select digestIT -> Verify MD5 Hash (or Calculate MD5 Hash).
If you select "Verify MD5 Hash" then you will be able to copy and paste the MD5 from MD5Sum page (linked to on the latest download page). If the checksums match, you will see: "Digest matches. Verification succeeded."
If you select "Calculate MD5 Hash" then you will need to visually compare the calculated MD5 with the one listed on the MD5Sum page (linked to on the latest download page).

Is there a program for the MAC...since we are a Mac Forum here, that will check the MD5 checksum of a file. I need to check a file before I root my phone and I'm not a huge techie. Thanks! Happy New Year!
