HISTORY
0.0.2
- ajax gets stinky: Flatulent.ajax! the result of this new
addition is
that the captcha itself doesn’t appear in the source file at all
- blowfish encoding for timebomb and captcha fields
- auto server key configuration using hostname and mac address
- improved noise algorithm
- improved character placement (chars shared edges to make
ocr’ing harder)
0.0.1
- initial version
