[cisco-voip] OT: storing passwords securely in unix scripts

[Lelio Fulgenzi]

i'd settle for a nebulous .exe file. 

i'm searching for compilers of scripts to see what i get. i shudder at the thought of writing something in C--.

It depends. 


Basic CUCM user/password combos are in a base 64 encoding so you could store that somewhere but I'm not sure how secure that would be. 


You could also look into encryption algorithms where your script could decode the stored value. 


Problem with either one lies in the fact anyone with access to your code could easily figure out the user/password combination. That is the downfall of scripts instead of a language which compiles a nebulous .exe

I may be thinking about this wrong, but if they aren't in plain text how is your script going to be able to use them? As far as I know you'd have to supply them back to the device in plain text which means they'd need to be some sort of decryptable encryption anyway which just puts you into security by obscurity mode. That may be enough for you but seems redundant to me and an extra step if the file the script is using is properly secured file permission wise.

this group is a smart bunch of cookies. anyone have any idea how to securely store passwords on unix/linux so that i can run scripts that require passwords? 

until Cisco builds SSH key pair recognition (or is it there already? ;), this seems like the only option. 

i don't want to be storing passwords in plain text regardless of how secure the directory might be. or at least avoid it if at all possible. 

thoughts?
