PKCS#7 Encryption Recipient Certificate List (0x0019).

This field MAY contain information about each of the certificates used in encryption processing and it can be used to identify who is allowed to decrypt encrypted files. This field should only appear in the archive extra data record. This field is not required and serves only to aid archive modifications by preserving public encryption key data. Individual security requirements may dictate that this data be omitted to deter information exposure.

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