Parameters.DeviceIoControl.InputBufferLength in the I/O stack location indicates the size, in bytes, of the buffer, which must be >= sizeof(AACS_SEND_CERTIFICATE).

Input Buffer Length

Parameters.DeviceIoControl.InputBufferLength in the I/O stack location indicates the size, in bytes, of the buffer, which must be >= sizeof(AACS_SEND_CERTIFICATE).

Output Buffer

None.

Output Buffer Length

None.

Status Block

The Information field is set to the number of bytes transferred. The Status field is set to STATUS_SUCCESS or possibly STATUS_INSUFFICIENT_RESOURCES.

Remarks

The IOCTL_AACS_SEND_CERTIFICATE request corresponds to the step in the Advanced Access Content System (AACS) authentication algorithm (AACS-Auth) in which the host sends its certificate and nonce to the drive. For a complete description of AACS-Auth, see the Advanced Access Content System, Introduction and Common Cryptographic Elements specification that is published by Advanced Access Content System Licensing Administrator (AACS LA).
