Parse QQ Messenger chat logs in VB6

Project requirements: Parse QQ Messenger chat logs using the QQ user account number to decrypt the logs (which use the Blowfish algorithm). Output can be a CSV file, must account for Unicode. Must be done in VB6 and the bidder must provide sample QQ chat logs, some in English and some in other languages (to show Unicode handling) to test the code (and provide them with the source code). Let me know if you have any questions.
