PostgreSQL with SSL

Hi,

I'm new on using SSL in PostgreSQL.

I've created a self-signed certificate using openssl and started the server
with ssl suport.

But I have some question, can you help me?

- There is any parameter to configure the path (and name) to certificate
(server.crt) and private key (server.key) like hba_file or ident_file in
postgresql.conf or any other?

- Is it possible to store the server.key in a ciphered file with triple-des
and configure the PostgreSQL to use a simetric-key to open it when it's
necessary?
Maybe I'm wrong but my server only works with I plain private key.

I'm trying to use the java keytool in place of openssl.
- I believe that it not possible to start the PostgreSQL server without
openssl (and ssl-dev package in debian), is it correct?

- When I create keys and certificates with keytool, it creates a java
keystore to store everything. I know how to export the certificate but I
don't know how to export the private key and when I use the keytool
certificate, the server crashes with this message:

FATAL: could not load server certificate file "server.crt": no start line

Sorry about too many questions, but anyone can help me to understand more
about ssl in PostgreSQL?
