Rijndael key maker?
There seem to be many win32 shareware programs for creating Rijndael symmetric keys, but is there a GNU way to do this in linux? What would the simplest approach be? The needed package(s)?

Wouldn't any random junk of the appropriate size work? But, you can encrypt with a randomly generated salt and a passphrase:
Code:
openssl enc -aes-256-cbc -salt -a -in plain.txt -out msg.crypt Code:
openssl enc -aes-256-cbc -salt -a -d -in msg.crypt -out plain.txt |
I am afraid this is my own ignorance of the whole key concept coming through. I am interested in using the fwknop single-packet authorization method of knocking into my firewall. The only windows client for this software requires the use of symmetric Rijndael keys. I presume that I need to put the key (that I create somehow) into the configuration file in the server, and then use the same (symmetric) key in the client when it tries to authenticate. I have an email into the author to see if he can point me at a tutorial on how to configure the SW. I suspected that I might be missing some pretty elementary steps on how to create the keys -- maybe I still am. Anyone point me at something that would educate me a little bit better about how to create a key for this sort of thing? Or is there no need to "create" a key at all?

The author replied to me. Evidently I am making more of things than I should. The symmetric "key" is nothing more than a password that is shared between server and client. No wonder I had so much trouble finding anything about this type of key...
