OpenSSH key management, Part 2

Author: JT Smith

"Many developers use the excellent OpenSSH as a secure, encrypted replacement for the venerable
telnet and rsh commands. One of OpenSSH's more intriguing features is its ability to authenticate users using
the RSA and DSA authentication protocols, which are based upon a pair of complementary numerical "keys".
One of the main appeals of RSA and DSA authentication is the promise of being able to establish connections
to remote systems without supplying a password. In this second article, Daniel [Robbins] introduces ssh-agent (a
private key cache) and keychain, a special bash script designed to make key-based authentication
incredibly convenient and flexible." Read the article at IBM developerWorks.
