When encryption is enabled, the encrypted data is +0x28 with size {remaining frame size}. This is encrypted with AES-128-CTR. The key is derived from the raw 0x20-bytes at +0x0. The CTR is {raw Counter above without byte-swap}, with the rest cleared to zeros. | |||
The content data at +0x48 follows, which has the size specified above (which must be >=0x500), where all fields are big-endian: | |||
