HashTab provides the hash algorithms’ in several formats. How is it used?
You can use HasTab by Implbits. HashTab installs a tab to the properties of a file.
Once you verify the file and upload it or email it, you can send the alphanumeric numbers to someone or post it on a website or blog prior to a file being downloaded. You can use the software to verify the numbers to see if you have the original hash.
Home computer users and students can use it for free. Link
