# Here's what I know about the secret key (starting with ASJN_i)
|
|
# *The secret key definitely contains the following information (or perhaps the information is stored at youtube's servers):
|
|
# -Video id
|
|
# -Offset
|
|
# -Sort
|
|
# *If the video id or sort in the ctoken contradicts the ASJN, the response is an error. The offset encoded outside the ASJN is ignored entirely.
|
|
# *The ASJN is base64 encoded data, indicated by the fact that the character after "ASJN_i" is one of ("0", "1", "2", "3")
|
|
# *The encoded data is not valid protobuf
|
|
# *The encoded data (after the 5 or so bytes that are always the same) is indistinguishable from random data according to a battery of randomness tests
|
|
# *The ASJN in the ctoken provided by a response changes in regular intervals of about a second or two.
|
|
# *Old ASJN's continue to work, and start at the same comment even if new comments have been posted since
|
|
# *The ASJN has no relation with any of the data in the response it came from
