Enabling Passwords and Encryption Keys's passphrase caching ability
allows you to perform many operations that require entering your
passphrase without reentering it every time
seahorse-daemon takes the place of
gpg-agent. Letting the cached passphrases
expire is usually a good idea. This will then require reentering your
passphrase, but adds security.

Passwords and Encryption Keys provides support for HKP and LDAP keyservers.
HKP Servers: HKP keyservers are ordinary Web-based keyservers such as the popular hkp://pgp.mit.edu:11371, also accessible at http://pgp.mit.edu.
LDAP Keyservers: LDAP keyservers are less common, but use the standard LDAP protocol to serve keys. ldap://keyserver.pgp.com is a good LDAP server.
You can or keyservers to be used using the buttons on the left. To add a new keyserver, set its type, host and port, if necessary.
Set whether you want to automatically publish your public keys and which keyserver to use. Set whether you want to autopmatically retrieve keys from keyservers and whether to synchronize modified keys with keyservers.
