What is the best way to calculate a checksum for a file that is on my machine?

Question

I\'m on a Windows machine and I want to run a checksum on the MySQL distribution I just got. It looks like there are products to download, an unsupported Microsoft tool, an

Answer 1

for sure the certutil is the best approach but there's a chance to hit windows xp/2003 machine without certutil command.There makecab command can be used which has its own hash algorithm - here the fileinf.bat which will output some info about the file including the checksum.

Answer 2

Checksum tabs: http://code.kliu.org/hashcheck/

This has worked great for me on windows for a while now. It allows easy copying and pasting of checksums. It has box to type/paste check sums from webpages and show matches or non matches quite well.

Answer 3

7-Zip can be used to generate hashes for files, folders of files, and trees of folders of files. 7-Zip is small footprint and a very useful compression utility. http://7-zip.org/

Answer 4

To calculate md5 of all the files in the current directory in windows 7

for %i in (*) DO CertUtil -hashfile %i MD5

Answer 5

QuickHash an open source tool supporting MD5, SHA1, SHA256, SHA512 and available for the Linux, Windows, and Apple Mac.

Answer 6

The CertUtil is a pre-installed Windows utility, that can be used to generate hash checksums:

CertUtil -hashfile pathToFileToCheck [HashAlgorithm]

HashAlgorithm choices: MD2 MD4 MD5 SHA1 SHA256 SHA384 SHA512

So for example, the following generates an MD5 checksum for the file C:\TEMP\MyDataFile.img:

CertUtil -hashfile C:\TEMP\MyDataFile.img MD5

To get output similar to *Nix systems you can add some PS magic:

$(CertUtil -hashfile C:\TEMP\MyDataFile.img MD5)[1] -replace " ",""
