When converting script to .NET Assembly, map checksum command to Session.CalculateFileChecksum method.

Parameters mapping: Command parameters alg and file maps to method parameters algorithm and path, respectively. You have to convert relative paths to absolute paths.

For example, the following script snippet:

cd /home/martinp/public_html
checksum sha-1 index.html

maps to the following PowerShell code:

Write-Host ([System.BitConverter]::ToString($session.CalculateFileChecksum("/home/martinp/public_html/index.html")))
