I have all my old .netscape and .mozilla directories for all my past installations of Netscape, Mozilla, and Firebox, going back to 1996. I've got cert.db, cert5.db, and cert7.db files.
I want to extract out all of the certs and keys that I had added to those databases, and then import them into my current ~/.mozilla database.
Reading the docs and futzing around with NSS signtool, certutil, and pk12util isn't getting me very far.
Surely there is a tool or technique do doing this...
