I am wondering as Trejkaz states, that this is just RC4 encryption, but it's a different version number, which gives us 4 instead of 0-3. I will download POI source and see if I can just change that line of code - that type=4 just does RC4 decryption and see if that works. Worth at shot. If it does, I'll post it up here. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
