More often than not I'm thinking about privacy and especially cryptographic functions that enable it.
At the beginning of the year I was in a truck waiting to be unloaded and started thinking about creating secure passwords from simple inputs. The best way for me was to use the terminal on Linux and Termux on my phone.
If you don't use Android or Ubuntu there are still ways to run a BASH script on Mac and Windows.
I've been using the script for a while and it's good for medium security applications. I have just published the script with an explanation of how to personalise it for yourself should you want to use it.
You'll find it on Github.
