Security Trailer:

The sec_trailer structure MUST be placed at the end of the PDU, including past stub data, when present. The sec_trailer structure MUST be 4-byte aligned with respect to the beginning of the PDU. Padding octets MUST be used to align the sec_trailer structure if its natural beginning is not already 4-byte aligned.

All PDUs that carry sec_trailer information share certain common fields: frag_length and auth_length. The beginning of the sec_trailer structure for each PDU MUST be calculated to start from offset (frag_length – auth_length – 8) from the beginning of the PDU.

Immediately after the sec_trailer structure, there MUST be a BLOB carrying the authentication information produced by the security provider. This BLOB is called the authentication token and MUST be of size auth_length. The size MUST also be equal to the length from the first octet immediately after the sec_trailer structure all the way to the end of the fragment; the two values MUST be the same.

A client or a server that (during composing of a PDU) has allocated more space for the authentication token than the security provider fills in SHOULD fill in the rest of the allocated space with zero octets. These zero octets are still considered to belong to the authentication token part of the PDU.

According to [MS-RPCE], auth_pad_length is the number of padding octets used to 4-byte align the security trailer, but in practice we get values up to 15, which indicates 16-byte alignment.
