I'm sorry, I forgot the code. I list the existing method, followed by my modified Pharo method below. I welcome any feedback.

This is a message intended for anyone who was on the Cryptography team. I recently ported it to Pharo and had to make changes to RandomGenerator class>>unpredictableStringsDo:. This certainly removed some uncertainty from the results of this message. My question is what should I do about that? This method seems to require non-headless, as it is checking the mouse point and such. This being a crypto cornerstone, what the best answer here.
Thank you, Robert
