The article goes on to describe how hard it would be to crack their, despite the title, non-plaintext password. What exactly is the point the author is trying to make here?
Oh, I see how the title could be confusing. I should probably use a title along the lines of "Using text passwords for encryption is safe enough"?
The point I was trying to make is that reasonably long password (six simple words) makes AES encryption with key transformations almost impossible to crack. (As opposed to my intuition).
Thanks for taking the time to write the comment. It's the first time I shared my article on HN.
