Since there is no pubring/secring as with PGP, mutt has to handle storage ad retrieval of keys/certs by itself. This is very basic right now, and stores keys and certificates in two different directories, both named as the hash-value retrieved from OpenSSL. There is an index file which contains mailbox-address keyid pair, and which can be manually edited. This one points to the location of the private keys. (S/MIME only)
