    How to Add Hash to Context Menu of Files in Windows 8 and Windows 10

    information   Information
    The Hash context menu uses the native Get-FileHash cmdlet in PowerShell to compute the hash value for a file by using a specified hash algorithm. A hash value is a unique value that corresponds to the content of the file. Rather than identifying the contents of a file by its file name, extension, or other designation, a hash assigns a unique value to the contents of a file. File names and extensions can be changed without altering the content of the file, and without changing the hash value. Similarly, the file's content can be changed without changing the name or extension. However, changing even a single character in the contents of a file changes the hash value of the file.

    The purpose of hash values is to provide a cryptographically-secure way to verify that the contents of a file have not been changed. While some hash algorithms, including MD5 and SHA1, are no longer considered secure against attack, the goal of a secure hash algorithm is to render it impossible to change the contents of a file-either by accident, or by malicious or unauthorized attempt-and maintain the same hash value. You can also use hash values to determine if two different files have exactly the same content. If the hash values of two files are identical, the contents of the files are also identical.

    The Hash context menu allows you to quickly see the SHA1, SHA256, SHA384, SHA512, MACTripleDES, MD5, and RIPEMD160 hash value of files.

    This tutorial will show you how to add or remove Hash to the context menu of all files for all users in Windows 8 and Windows 10.

    While you must be signed in as an administrator to be able to add or remove the Hash context menu, all users can use the context menu.

    Note   Note
    Hash context menu usage: (once added)
    1. Select one or more files you want to see the hash value(s) of.
    2. Right click or press and hold on the selected file(s).
    3. Click/tap on Hash in the context menu.
    4. Click/tap on the SHA1, SHA256, SHA384, SHA512, MACTripleDES, MD5, RIPEMD160, or Show all algorithm you want to see the hash value of for the selected file(s).
    5. A PowerShell window will now open for each selected file showing you their hash value.
