How can I use wsman on Linux without passing passwords in plaintext?

Question

I'm using libwsman/wsmancli and libcurl4-32bit to run wsman commands from a linux box against the iDracs of some Dell boxes I have. The problem I'm running into is authentication requires plaintext password and username. This is fine if I use it from the commandline; however, I'm using the dell python wrapper (basically just a wrapper for subprocess) execute the commands in a script I've written. So, every instance where I run a command, I need to pass my password in plaintext.. Is there a way around this? The only alternative I can think of is to add a less-privileged user to each of the iDracs; but that doesn't resolve the underlying issue..
