Cmdlet Idea: Grant-PrivateKeyAccess

[Viajaz]

A Cmdlet which grants Permissions to the Private Key of a Certificate in the Certificate Store would be useful.

Example:
$Certificate could perhaps be location such as cert:\LocalMachine\My\FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF or perhaps just thumbprint?
$Identity would be the security principal (eg: NETWORK SERVICE or DOMAIN\user)
Permission parameter being either FullControl or Read

Grant-PrivateKeyAccess -Certificate $Certificate -Identity $Identity -Permission 'FullControl'

There is a Question-and-Answers on StackOverflow (How to Grant permission to user on Certificate private key using powershell?) on how to grant permissions but seemingly, anecdotally, doesn't seem reliable across platforms and use-cases, I also wonder if the example code provide would work with non-RSA keys but an answer I provided to another StackOverflow Question is useful in obtaining the absolute path of a Certificate Container.

Such a Cmdlet would be useful in order to automate configuration of key access after Certificate Installation as part of installation of a service or other such software.

Hallo, many thanks for your feedback. Have a look at this. I plan to integrate this into the module in an upcoming version.

In regards to https://github.com/Sleepw4lker/OcspManager/blob/master/lib/Set-CertificatePrivateKeyPermissions.ps1
It could be useful to have Parameter $Certificate be set to accept ValueFromPipeline when you port it over as well as another parameter to specify System.Security.AccessControl.CryptoKeyRights

This works for regular (software based keys) and also for keys located in a HSM
