iTunes 4.5 Authentication Cracked
Found on Slashdot on Thursday, 29 April 2004

Yesterday, Apple released iTunes 4.5, which deliberately broke the 4.2 authentication scheme, which had been successfully reverse-engineered. However, crazney has been at it again, and within 24 hours of downloading iTunes 4.5, has broken the new scheme, and added more features to this library along the way. If you want to incorporate iTMS support in your program, give libopendaap a go!
That's what I call quick. It would be interesting to know how long it took Apple to create the new authentication. I doubt it took them just a few hours, so the 24 hours crazney needed were nothing compared to Apple's expenses.
