Release Notes

This initial version includes functions for hunts, flows, client handling, search functionality and label handling. All function takes the computer name as input which is then converted to the needed client id internally. If multiple client id's are available for one client then the functions use just the latest seen client (LastSeenOn property).

Most functions allow returning plain JSON instead of the converted GRR object. Various functions has pipeline support. See help and the markdown documentation. The configuration allows using certificate authentication.

Create a Configuration.ps1 file in the root folder of the project. Set the following variables as needed:

**********************
# Ignore certificate errors - if set to $true certificate errors are ignored
$GRRIgnoreCertificateErrors = $false

# Client certificate issuer - if set the corresponding client certificate is used
# Otherwise the client certificate from the given issuer is used.
$GRRClientCertIssuer = "issuer of the certificate"

# GRR URL
$GRRUrl = ...
**********************
