Answer 1

I like to use HashMyFiles for windows.

Answer 2

Just to add another option for Windows users, the Get-FileHash PowerShell cmdlet can be used (https://technet.microsoft.com/en-us/library/dn520872.aspx).

Example usage: Get-FileHash MyImage.iso -Algorithm MD5

If all you're after is just the raw hash then: (Get-FileHash MyImage.iso -Algorithm MD5).Hash

Answer 3

I personally use Cygwin, which puts the entire smörgåsbord of Linux utilities at my fingertip --- there's md5sum and all the cryptographic digests supported by OpenSSL. Alternatively, you can also use a Windows distribution of OpenSSL (the "light" version is only a 1 MB installer).

Answer 4

On MySQL.com, MD5s are listed alongside each file that you can download. For instance, MySQL "Windows Essentials" 5.1 is 528c89c37b3a6f0bd34480000a56c372.

You can download md5 (md5.exe), a command line tool that will calculate the MD5 of any file that you have locally. MD5 is just like any other cryptographic hash function, which means that a given array of bytes will always produce the same hash. That means if your downloaded MySQL zip file (or whatever) has the same MD5 as they post on their site, you have the exact same file.

Answer 5

Download fciv.exe directly from http://www.microsoft.com/en-us/download/confirmation.aspx?id=11533

shell> fciv.exe [yourfile]

will give you md5 by default.

You can read up the help file fciv.exe -h

The Powershell utility Get-FileHash worked perfectly for me.
