Is there a built-in checksum utility on Windows 7?

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 PowerShell magic:

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

PowerShell version 4 and up includes the Get-FileHash cmdlet.

powershell get-filehash -algorithm md5 <file_to_check>

Use doskey to make a persistent alias that's easier to remember.

doskey sha1sum=powershell get-filehash -algorithm sha1 "$1"

doskey md5sum=powershell get-filehash -algorithm md5 "$1"

Microsoft File Checksum Integrity Verifier. It can compute MD5 and SHA-1 hash values.

Download, extract the files, then open a command prompt, go to the extracted path and then type the following command:

fciv -md5 filepath\filename.extension
For example:

fciv -md5 d:\programs\setup.exe
