[FFmpeg-devel] ASF file decryption

[Ruchika Chaddha]

Hi,

 I have to decrypt a DRMed ASF file (.wma), I want to know which portion of
ASF file is protected? Is it the entire data object (excluding data object
header)?  I have the keys to decrypt but don't know where to start
decrypting data from. Also, is the whole content decrypted with same
symmetric key?

 Your reply would be highly appreciated,

Thanks & Regards,

Ruchika
