Building on my last post on stateful-process-command-executor this post will cover how you can leverage that node.js module to expose the capabilities of Powershell cmdlets over a REST api presented through an AngularJS interface.

Please see: https://github.com/bitsofinfo/powershell-credential-encryption-tools Recently I had the need to store some credentials for a powershell script (i.e. credentials that I ultimately needed in a PSCredential object).

Generating Java classes for the Azure AD Graph API

Posted on July 22, 2014July 22, 2014 by bitsofinfo
