Contest Brief

I created a simple application which allows a team to share credentials. As example one person will enter username/password into this system and another can get it out of there and use it.

This is internal project for our company. The application is called "Credzilla" (play of words "credential" and "godzilla").

I am looking for a logo for this application.
This would be great, if the logo can depict a godzilla and something related to credentials (a lock, a key or something like that). However, I am open for other ideas.
