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  and probably other options   I m wondering if there is a consensus for the best tool to use   This may be a really easy question  I ve just never run a checksum routine before

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

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

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

Note that the above solutions will not tell you if your installation is correct only if your install exe is correct  you can trust it to produce a correct install    You would need MD5 sums for each file folder to test if the installed code has been messed with after the install completed   WinMerg is useful to compare two installs  on two different machines perhaps  to see if one has been changed or why one is broken
