SDU Tools: ROT13 Encode and Decode in SQL Server T-SQL

If you used computers much in the 1980's or 1990's you'll remember jokes that circulated all the time, but encoded in ROT13. It was a type of Caesar Cypher or Shift Cypher where the letters in the original words were shifted by a fixed number of positions in the alphabet to create the cyphertext.

ROT13 was a specific type of shift cypher where, for our alphabet of 26 characters, a 13 character shift is applied. That means that the same function can be used to encode text and then to decode the same text.

So, in our free SDU Tools for developers and DBAs, we added a simple function that implements ROT13. You can use the tools as a set or use them as examples of how to write the T-SQL code.
