This small powershell script creates an Base64 encode of the username and, or password.
# Base64 encode the username "myusername" $userBytes = [System.Text.Encoding]::UTF8.GetBytes("myusername@012345"); [System.Convert]::ToBase64String($userBytes) # Base64 encode the password "mypassword" $userBytes = [System.Text.Encoding]::UTF8.GetBytes("mypassword"); [System.Convert]::ToBase64String($userBytes) # Base64 encode the myusername & mypassword into one line. $auth = [System.Text.Encoding]::UTF8.GetBytes("myusername@012345:mypassword"); [System.Convert]::ToBase64String($auth)
