I want to know, how often do you verify file hashes?

Most of us are continuously downloading files from the internet.  With many of these files there is a posted hash value to verify the integrity of the file.  How often do you actually make sure that the file’s hash value is equal to what is posted?

If you are using windows there is a really convenient, easy to use program called BD File Hash.  This super small, .NET based application will calculate and verify file hashes using MD5, SHA-1, and SHA-256 algorithms.  If there is a different type of hash you require, leave me a comment and I will see if can be added to the application.

BD File Hash has been found 100% malware free by Softpedia.

I just finished a new file hashing tool, BD File Hash, which is hosted on CodePlex under the Microsoft Public License (Ms-PL).

The goal behind this Windows tool is an easier way to verify files you download from the internet.  Many applications, ISO’s, and other files usually list a hash with them.  This hash is used to verify the file you downloaded is the same file the author meant you to download.  It prevents you from using corrupt or exploited downloads by allowing you to verify the file before you use it.

The problem I had with most file hashing tools, is that they needed to be run from a command line, or you had to open the hash value into a text editor and copy/paste it into the hashing application to be compared. So I wanted BD File Hash to be a convenient way to verify files using hashes.

BD File Hash has the following capabilities:

  • Right click any file and select BD File Hash from your Send To menu
  • Use a file picker to select the file with the authors hash value, it will automatically be parsed from the file and entered into the BD File has application
  • Easily hash to files to see if they are the same
  • Supports MD5, SHA-1, and SHA-256
    • Please recommend any other hashing algorithms you may need.
  • Save your default hash type to the one you use most often

BD File Hash requirements:

  • .NET 3.5 SP1
  • Windows Installer 3.1
