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,
