Revision (1 byte): An 8-bit unsigned integer that specifies the revision level of the SID. This value MUST be set to 0x01.

SubAuthorityCount (1 byte): An 8-bit unsigned integer that specifies the number of elements in the SubAuthority array. The maximum number of elements allowed is 15.

IdentifierAuthority (6 bytes): A SID_IDENTIFIER_AUTHORITY structure that indicates the authority under which the SID was created. It describes the entity that created the SID. The Identifier Authority value {0,0,0,0,0,5} denotes SIDs created by the NT SID authority.

SubAuthority (variable): A variable length array of unsigned 32-bit integers that uniquely identifies a principal relative to the IdentifierAuthority. Its length is determined by SubAuthorityCount.
