This module can determine what public keys are configured for
key-based authentication across a range of machines, users, and
sets of known keys. The SSH protocol indicates whether a particular
key is accepted prior to the client performing the actual signed
authentication request. To use this module, a text file containing
one or more SSH keys should be provided. These can be private or
public, so long as no passphrase is set on the private keys.
2012-01-05 20:10:49 +00:00
If you have loaded a database plugin and connected to a database
this module will record authorized public keys and hosts so you can
track your process.
Key files may be a single public (unencrypted) key, or several public
keys concatenated together as an ASCII text file. Non-key data should be
silently ignored. Private keys will only utilize the public key component
stored within the key file.

Squashed commit of the following: commit 036d2eb61500da7e161f50d348a44fbf615f6e17 Author: Tod Beardsley <todb@metasploit.com> Date: Sun Jan 8 22:23:32 2012 -0600 Updates ssh credentials to easily find common keys Instead of making the modules do all the work of cross-checking keys, this introduces a few new methods to the Cred model to make this more universal. Also includes the long-overdue workspace() method for credentials. So far, nothing actually implements it, but it's nice that it's there now. commit c28430a721fc6272e48329bed902dd5853b4a75a Author: Tod Beardsley <todb@metasploit.com> Date: Sun Jan 8 20:10:40 2012 -0600 Adding back cross-checking for privkeys. Needs to test to see if anything depends on order, but should be okay to mark up the privkey proof with this as well. commit dd3563995d4d3c015173e730eebacf471c671b4f Author: Tod Beardsley <todb@metasploit.com> Date: Sun Jan 8 16:49:56 2012 -0600 Add SSHKey gem, convert PEM pubkeys to SSH pubkeys commit 11fc363ebda7bda2c3ad6d940299bf4cbafac6fd Author: Tod Beardsley <todb@metasploit.com> Date: Sun Jan 8 13:51:55 2012 -0600 Store pubkeys as loot for reuse.

This last thing Leads to some double accounting of creds, so I'm not super-thrilled, but it sure makes searching for ssh_pubkey types a lot easier.... maybe a better solution is to just have a special method for the cred model, though.
