X.509 Certificate ID and Signature for individual file (0x0015).

This field contains the information about which certificate in the PKCS#7 store was used to sign a particular file. It also contains the signature data. This field can appear multiple times, but can only appear once per certificate.

Note: all fields stored in Intel low-byte/high-byte order.
