Reset Evolution NSS certificate DB

I set a password on my Evolution certificate database in Xubuntu 14.10 Utopic, but must have typed something different than what I intended, so I wasn't able to manage any of my S/MIME certificates. To reset the password, I deleted the files that are related to storing the NSS database in ~/.local/share/evolution. cert8.db key3.db secmod.db Then I was able to go through Edit -> Preferences -> Certificates -> Import to manage my S/MIME library.
