$SSL_DIR/CA/crt.pem                   # CA certificate that signed
                                        all certificates.
$SSL_DIR/CA/private/key.pem           # CA private key
                                        (on server only)
$SSL_DIR/me/crt.pem                   # public certificate of the host
$SSL_DIR/me/private/key.pem           # private key of the host
$SSL_DIR/me/fingerprint               # fingerprint of my certificate
$SSL_DIR/remote/HOSTNAME/fingerprint  # fingerprint of the HOSTNAME

On the HOSTNAME host, $SSL_DIR/remote/HOSTNAME is a symbolic link to ../me.
