A handy cmdline to make a checksum of a file like
md5sum in Linux.There is a built-in utility in Windows OS to make a checksum of a file.
For this, the certutil is a built-in cmdline tool that can generate different hashes for a file.
Checksum#
MD5 hash checksum (md5sum):
C:\> certutil -hashfile c:\windows\explorer.exe md5
MD5 hash of c:\windows\explorer.exe:
24ad59abaf730e71bc865922d8596008
CertUtil: -hashfile command completed successfully.SHA256 hash checksum (sha256sum):
C:\> certutil -hashfile c:\windows\explorer.exe sha256
SHA256 hash of c:\windows\explorer.exe:
988a56d897915315eef9ca679b3bc8adfcecf5e227aea99aaa1817620520e97e
CertUtil: -hashfile command completed successfully.Hash Algorithms#
certutil supports 7 hash algorithms:
