3.2.1.4.2.1.4.6.3 Serial Numbers Based on Config_High_Serial_String

  • Article

Construct a serial number that consists of these parts (from low byte to high):

  • Bytes 0-3: The 4-byte little-endian value of the request ID (the value of the Request_Request_ID column in the Request table generated in section 3.2.1.4.2.1.4.4).

  • Bytes 4-5: The 2-byte little-endian value of the index of the last row of the Signing_Cert table.

  • Bytes 6-18: Up to 13 initial bytes of the numeric value of Config_High_Serial_String. To obtain a numeric value, convert the string to a multi-byte integer by interpreting each pair of characters as hexadecimal string representation of a single byte while ignoring any spaces or tabs. The order of bytes in the string is high to low.
