Since we need to create a lot of new values for different types of hash algorithms, to make things easier, I made the reg file for you. Just follow the steps as is and it will be done in no time.ġ. Though sounds complicated, it is very easy to do. We can add all these algorithms as sub-options to the Hash option in the right-click menu.
The cmdlet supports several different hash algorithms like MD5, MACTripleDES, SHA1, SHA256, SHA384, SHA512, etc. Windows uses PowerShell’s Get-FileHash cmdlet to give you the hash value. Add Hash Option to Right-click Context Menu This allows you to find the hash value with just two clicks. However, to makes things easier, you can add the Hash option to the right-click context menu. Generally, you have to manually execute commands to get different hash values. In addition to that, you can also use the hash values to differentiate between two identical files. Simply put, a hash value gives you a cryptographically secure way to determine the file integrity. Since the value is generated using the file contents, if the file is modified in any way, no matter how tiny the change is, the hash value will change automatically.
Note: Earlier NX-OS versions may not have the sha512sum option but md5sum should be present on all versions.In case you don’t know, a hash value is an algorithmically generated value using the file contents rather than superficial things like file name and extension. This confirms the validity of the file transferred to the switch. MDSswitch# show file bootflash:m9100-s5ek9-kickstart-mz.8.1.1.bin md5sum Sha512sum Displays SHA512 checksum for a file Sha256sum Displays SHA256 checksum for a file Once the file is transferred to the MDS or Nexus bootflash, you can check the md5sum or sha512sum with: MDSswitch# show file bootflash:m9100-s5ek9-kickstart-mz.8.1.1.bin ? On a Linux or Unix machine, use md5sum or sha512sum typically located in /usr/bin i.e. On a Mac, you can use md5 or shasum -a 512 to achieve this: $ md5 m9100-s5ek9-kickstart-mz.8.1.1.bin Using the above m9100-s5ek9-kickstart-mz.8.1.1.bin file as an example: c:\Temp>certutil -hashfile m9100-s5ek9-kickstart-mz.8.1.1.bin MD5
On a Windows PC, there is an inbuilt tool certutil which you can use with the MD5 or SHA512 hash algorithms (amongst others) to establish the unique checksum of any file.
