TIL: How to generate checksum?

Checksums work like a fingerprint. It is used to verify file integrity. If the files have the same checksums, then they are identical. It can also be used to check if the file has been previously scanned as malicious.

On Windows:

1. certutil:

    certutil -hashfile <filepath> SHA256
   

   

2. Get-FileHash

    Get-FileHash <filepath> -Algorithm SHA256
   

   

On Linux/macOS:

1. sha256sum

    sha256sum <filepath>
   

   

2. shasum

    shasum -a 256 <filepath>
   

   

The file hash can also be checked on VirusTotal and InQuest
