This is a custom reference code generator developed by Jevi to make unique index card numbers for my research log database.

Reference code are created by appending the following:
1) the index letter of the topic grouping from the dropdown,
2) the caluclation of the javascript equivalent of javahash on source title, that is then hashed again and padded to make a 256 colour, and
3) the first 8 characters of title ciphered using rot13.
