On his birthday last year (2013), a friend of mine posted a cipher in a group to which I belong. He said whoever cracks it would get a prize worth a bundle.
The cipher was:
Ism mgyc ksg g Gcwmo 4 Ougcaemsgc! Cugyi ———@augyi.esu osc ismc eccocga
(I have replaced his email address (which was known to me) with ‘———‘)
He said: The only clue is this: the letters used on fast-forward buttons on old tape recorders.
1. How old am I?
2. Museveni, a third.
Then he said we would need a tool to crack the cipher.
I Googled cipher tools and eventually landed on:

This changed the code to:

Yup! I won a Nexus 4 smartphone! Beating out a number of other competitors who were trying to crack the code. (One friend cracked it in seconds and was barred from participating).
