How to remove / remove certificates from Mono certificate stores My and trusts?

I added the certificate to the Mono 3.2.8 repository using the following command on Linux.

certmgr -add -c -m My mycert.cer

Added certificate can be viewed

  certmgr -list -c -m My mycert.cer

Use the following command to delete a previously added certificate. But the certificate is not deleted. The team did not display any error messages.

  certmgr -del -c -m My mycert.cer

  • Where does Mono store certificate data on the system?

I tried to add a certificate using the mozroots command, but by default it tries to add a certificate to the store’s address book. (I could not find the command to remove the certificate from the My or Trust store)

  mozroots --import --machine --sync certmgr -ssl -m https://test:1200/service

  • How to remove a certificate from stores (My, CA, Trust, etc.)?

Running this command:

 certmgr -del -c -v -m Trust CERTHASH

Where CERTHASH is the number in Unique Hash (you can extract this value certmgr -list -c -v -m YOURSTORE , see the example at the end of my answer):

  1. Where does Mono store certificate data on the system?

In some of these ways:

 /usr/share/.mono/certs/ ~/.config/.mono/certs/

Examples:

Add a new certificate to the Trust store (valid stores: My , AddressBook , CA , Trust and Disallowed ):

 me@myserver :~$ certmgr -add -c -v -m Trust google.cer Mono Certificate Manager - version 3.2.6.0 Manage X.509 certificates and CRL from stores. Copyright 2002, 2003 Motus Technologies. Copyright 2004-2008 Novell. BSD licensed. 1 certificate(s) added to store Trust.
