// Implement a Cmdlet type so we can utilize the WriteProgress() method and get PowerShell's native
// progress bar overlayed while uploading. Using Console.Write() and trying to manually move/set
// the cursor position doesn't work in the PowerShell ISE, nor on Linux.
//
// Also unfortunate is the fact that on Linux, the HttpWebRequest.AllowWriteStreamBuffering cannot
// be set to false. https://github.com/dotnet/runtime/issues/18632
// With .NET Core (whoes source code is now under .NET Rumtime) on Linux, the HttpWebRequest actually
// uses the HttpClient under the hood (with the .NET Framewrok it's the other way around).
// https://github.com/dotnet/runtime/blob/master/src/libraries/System.Net.Requests/src/System/Net/HttpWebRequest.cs
// And when getting the request stream (see the InternalGetRequestStream() method), it simply creates
// a new instance of the RequestStream object
// https://github.com/dotnet/runtime/blob/b783c5b42b3d35ef793a9d7aa8c06bcc27567e8d/src/libraries/System.Net.Requests/src/System/Net/RequestStream.cs
// Which states in the comments the use of a MemoryStream and it being inefficient for uploading
// large amounts of data. There is no way to change this or override it.
//
// Therefore, we'd be back to the same original problem that made us switch to this embedded code
// in the first place, namely, uploading a patch file would use as much memory as the size of the file.
//
// So the next hurdle is switching to use the HttpClient class. But with that, there was no native
// support for being able to compute the progress while uploading. So we had to implement another
// custom class. Then, there was a problem with trying to use the WriteProgress() method from outside
// the ProcessRecord() method of the Cmdlet and making any async calls synchronous to ensure that we
// stay on the same thread.

.DESCRIPTION
Upload a patch to a Safeguard appliance via the Web API, or use a previously staged patch. If you don't specify
to use the currently staged patch, if one exists, it will be overwritten. If successful and on the primary
appliance, the patch will automatically be distributed to other appliances in the cluster. Upon distribution,
also removes any patch on the other appliance and stages the specified patch. Then, if there are no patch
precondition warnings or errors (on applicable versions of Safeguard), you will be prompted to install the patch.

.SYNOPSIS
Create a new backup on a Safeguard appliance via the Web API.
 
.DESCRIPTION
This cmdlet will initiate the creation of a new backup on a Safeguard
appliance. The backup can be downloaded using the Export-SafeguardBackup
cmdlet or archived using the Save-SafeguardBackupToArchive cmdlet. The
Import-SafeguardBackup cmdlet can be used to upload the backup later
to a Safeguard appliance. The Restore-SafeguardBackup cmdlet can be used
to restore a backup that has been uploaded.

.SYNOPSIS
Verify the contents of an audit log archive file.
 
.DESCRIPTION
This cmdlet will read the ZIP file archive exported from Safeguard and verify
the signature of each of the JSON files inside the archive. By default this

IP address or hostname of a Safeguard appliance.
 
.PARAMETER AccessToken
A string containing the bearer token to be used with Safeguard Web API.
 
.PARAMETER Insecure
Ignore verification of Safeguard appliance SSL certificate.
 
.PARAMETER ArchiveZip
A string containing the file path to a Safeguard audit log archive file.
 
.PARAMETER SigningCertificate
A string containing the file path to a certificate that will be used to verify signatures.
 
.INPUTS
None.
 
.OUTPUTS
Boolean from Safeguard Web API.
