Confirm existing recovery key works

I have an old recovery key from 2020. I'm not sure if it is still valid. I've turned FileVault on and off over the years and I've had to start new Time Machine disks several times. I've also had to move all data from a corrupted user account to a new account. I don't know how these events may have affected encryption. How can I check to see if this recovery key works without losing or inadvertently changing my password or the key itself? Thank you.

Verify FileVault status from Terminal.app copy and paste:

fdesetup status

Verify FileVault Recovery Key is current ....from the Terminal.app copy and paste;

sudo fdesetup validaterecovery

(note: your psswd will not echo on screen type it in anyway, use the enter\return key to proceed.)

“Enter the current recovery key” copy and paste the Recovery Key and press Enter\Return key to proceed

here you will see:

—True if the Recovery Key the current key;

—False if no
