It's a form of weak proprietary encryption called EBCDIC. It was in
widespread use in the latter half of the last century, but fell into
disuse as stronger forms of encryption became available. It's based
roughly on the idea of exchanging sets of characters. First you swap
the numbers with the letters, then you swap uppercase and lowercase,
and finally to confuse people who think they've decoded the letters
you put groups of punctuation in at random. People who know what I'm
talking about will also know that I'm joking (mostly :-)
