How to Get File Hash in PowerShell - Active Directory Tools

To get file hash in PowerShell, you can use the Get-FileHash cmdlet. This command provides different hash algorithms such as SHA1, SHA256, SHA384 and MD5.

The following method shows how you can do it in PowerShell.

Method 1: Get file hash in PowerShell

# specify the path to the file
$filePath = "C:\temp\log\system_log.txt"

# Get the hash of the file

$fileHash = Get-Hash -Path $filePath -Algorithm SHA256

# Output the file hash
Write-Output $fileHash.Hash

This example will display the hash of the file.

The following example shows how you can use this method.

Get File Hash Using Get-FileHash in PowerShell

You can get file hash in PowerShell by using the Get-FileHash cmdlet. The Get-FileHash command uses the -Algorithm parameter to specify the algorithm to calculate the hash value of the specified file.

# specify the path to the file
$filePath = "C:\temp\log\system_log.txt"

# Get the hash of the file

$fileHash = Get-FileHash -Path $filePath -Algorithm SHA256

# Output the file hash
Write-Output $fileHash.Hash

Output:

In this PowerShell script, the $filePath variable stores the path to the file for which you want to calculate the hash.

The Get-FileHash cmdlet calculates the hash of the file specified by $filePath using the algorithm SHA256 and stores the result in the $fileHash variable.

Finally, we can output the hash value of the file using the Write-Output cmdlet.

After running the above script, PowerShell will output the hash value of the specified file.
