Listing Available Private Keys
 The SOCKS Proxy will search and use keys from the following locations:
 
-  keys defined in the 
key-store element in the /opt/tectia/etc/ssh-socks-proxy-config.xml file
 -  keys defined in the 
key-store element in the $HOME/.ssh2/ssh-socks-proxy-config.xml file
 -  keys defined in the 
$HOME/.ssh2/identification file
 -  keys found in the 
$HOME/.ssh2 directory
 
 
 To get the SSHSP user's key information, you need to run 
ssh-socks-proxy-ctl as a UID 0 user on the USS side and give the 
-a /tmp/ssh-<user who started ssh-socks-proxy>/ssh-socks-proxy 
option to it.
 To list the public-key pairs that are available for the SOCKS Proxy, give the 
following command:
 
# /opt/tectia/bin/ssh-socks-proxy-ctl list-keys -a /tmp/ssh-SSHSP/ssh-socks-proxy
 The command prints a list of available private keys, showing basic key 
attributes such as key type, size and possible file name or key provider 
information. Also fingerprint and key identifier are displayed. The key 
identifier is a number that is used by other ssh-socks-proxy-ctl 
commands to identify the private key uniquely.
 Running the command with the -s option produces a shorter output, 
for example (key hash value omitted):
 
# ssh-socks-proxy-ctl list-keys -s -a /tmp/ssh-SSHSP/ssh-socks-proxy
#2 ... ssh-dss /home/user1/.ssh2/id_dsa_1024_a dsa 1024
#1 ... ssh-rsa /home/user1/.ssh2/id_rsa_1536_a rsa 1536

 The first number on the line is the key identifier.
