The ENCRYPTION_CERTIFICATE_HASH_LIST type is used to represent a set of certificate hashes.

 typedef struct _ENCRYPTION_CERTIFICATE_HASH_LIST {
   [range(0,500)] DWORD nCert_Hash;
   [size_is(nCert_Hash,)] ENCRYPTION_CERTIFICATE_HASH** Users;
 } ENCRYPTION_CERTIFICATE_HASH_LIST;

nCert_Hash: The number of certificate hashes in the list.

Users: A pointer to an array of pointers to ENCRYPTION_CERTIFICATE_HASH (2.2.10) structures. This array is of size nCert_Hash.<24>
