In Lotus Notes, this is done via the PKI (Public Key Infrastructure) of your existing Lotus Notes ID.
Your client signs messages to other Lotus Notes recipients with your public key.
Error messages are not only annoyances to Lotus Notes/Domino users and administrators.
They are also calls to action to fix issues with a Notes client or Domino server.
As a result the user will be unable to email a safe copy of the ID to the administrator.
Note the following: The DC release supports RSA-PSS Signing on Windows (April, 2017) and Macintosh (August 2017).
RSA-PSS is a new signature scheme that is based on the RSA cryptosystem and provides increased security assurance.
You have a Lotus Notes user ID that has expired and you would like to manually recertify it.
The ID can open Notes, because the password is valid, but the user cannot do anything else, as the end date has expired.
