What you are talking about is called SSH agent/key forwarding which SecureCRT
supports and makes use of by default (See Connecton -> SSH2 -> Advanced -> 
Enable OpenSSH Agent Forwarding in your session properties). Have a look at
the (-A -a) options in man ssh and the ForwardAgent option in man ssh_config.
Putty has a similar feature but it is not enabled by default (see pagent)
