The game starts at 3:30PM - if you stumble across this before, good for you,
just don't write code until it starts - and entries will be accepted via tweets
with the [#devfriday
][2] hashtag until the next Developer Friday. In the case
that no entries are made before then, [Mark][4] will win by default. To participate
you need to have been to at least one [Developer Friday][3].
Goal: Webservice to encrypt/decrypt data using the [Four-square][1] cipher.
Any character not matching [a-pr-z]
should be removed. For example quick test
should be treated as uicktest
.
