It depends on what you're trying to achieve - password protection, 
concealing data, encrypting a connection.

The md5() function is built-in, and may be suitable for password 
protection on a simple web app.

The pg_crypto module in the contrib directory of the source distribution 
(or the extras package of your particular distribution) gives examples 
of various encryption and hashing functions it supports.

Encrypted connections are handled by the ssl library - see Chapter 20. 
"Client Authentication" in the manuals.
