One time a friend needed to come up with a password for something we were working on and I suggested the technique of using the first letters of a phrase that you know, so for example you might pick “That’s one small step for a man” which would give you the password “tossfam.”

So my friend thought about it for a moment and suggested “iatvmoammg.”

I’ll let that sit with you for a minute…

Still thinking?

Figured it out?

I did, to the surprise of both of us.

It’s a line from a popular musical play by Gilbert and Sullivan, The Pirates of Penzance: “I am the very model of a modern Major General” I have no idea whether it was unusual or not that I figured that out; so here are several more. Feel free to post in the comments if you figure them out (or not) and how easy or hard they are. All of them are common sayings, quotes, or phrases.

I think these are easier:

tbontbtitq

fsasyaofbfotcann

tgiagotos

waliaysaysays

anwyccdfyawycdfyc

iwtbotiwtwot

I think these are harder:

arsgnm

totwhtfifi

aycdicdbicdabty

mwchiny

altaiagffa

twdmar

gammd

idnlgeahidnltsia

Edit: Peter has a good idea with rot-13. You can access a tool to apply/remove rot-13 encoding here.
