Certutil is a versatile command-line utility in Windows that can be used for various tasks, including generating cryptographic hashes for files. This is particularly useful for verifying the integrity and authenticity of files by comparing their hash values.

Generating a Hash for a File

To generate a hash for a file using Certutil, you can use the -hashfile option followed by the file path and the desired hash algorithm. Certutil supports multiple hash algorithms such as MD5, SHA1, SHA256, SHA384, and SHA512.

Example Command

Replace path\to\your\file with the actual path to your file and [HashAlgorithm] with the desired algorithm (e.g., MD5, SHA256).

Example Usage

This command will generate and display the SHA256 hash of the specified file.

Output

The output will display the hash value of the file, which you can use to verify the file's integrity by comparing it with a known hash value.
