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 " ",""
