# ssh-cipher-benchmark.sh - Assesses speed of SSH encryption between specific hosts.
# Usage:
# ssh-cipher-benchmark.sh <remotehost> [ciphers]
# Default ciphers: all we can find...
#
# Note: In some cases, the first cipher tested runs faster than the others, regardless of order.
# Cause of this is not known, but changing the order of testing shows it to be true.  Run the
# first one twice if you suspect this.  Perhaps it is due to buffering?

Better SSH Authorized Keys Management

A seemingly common problem that people encounter is how to handle all of your users authorized_keys file.

People struggle over management, ensuring that users only have specific keys in the authorized_keys file or even a method for expiring keys. A centralized key management system could help provide all of this functionality with a little scripting.

One piece of functionality overlooked in OpenSSH is the AuthorizedKeysCommand configuration keyword. This configuration allows you to specify a command that will run during login to retrieve a users public key file from a remote source and perform validation just as if the authorized_keys file was local.

Here is an example directory structure for a set of users with SSH public keys that can be shared out via a web server:
