How do you produce a hash value for a file?
Issue:
My company wants to conform to NERC requirements. How do you produce a hash value for a file?
Product Line:
All Scheider devices and software
Environment:
Windows 7, 10
Resolution:
Navigate to the folder where the files you want to generate a hash algorithm for are located.
1. Open a command prompt.
2. Type : cd <path to file>. Simply copy and paste the path to file, right click and paste (CTL+V will not work). Press Enter
3. Type CertUtil –hashfile [space]
4. Then [Tab] key until filename shows up
5. Then add a [space] and “SHA256” [Enter]
In a CMD prompt this is how it should look: CertUtil -hashfile <path/file> < hash algorithm >
Where <hash algorithm> can be: [MD2, MD4, MD5, SHA1, SHA256, SHA512]
On Windows 7, the <hash algorithm> is case-sensitive. Be sure to type, for example, “MD5”, not “md5”. On Windows 8.1 and 10, case doesn’t matter.
Example: c:\User\myuserid> CertUtil -hashfile myfile.x SHA256
Alternatively, you can simply navigate to the folder where the file is located, then right click on the file and select "CRC SHA".
Then select the type of hash you want, once the type of hash is selected, a popup will show with the requested hash value.
From the CRC SHA selection screen, if you select * then all available types of hash will be shown.
