+ASN1_INTEGER_get_uint64() is similar to ASN1_INTEGER_get_int64_t() except it
+converts to a B<uint64_t> type and an error is returned if the passed integer
+is negative.

 ASN1_INTEGER_get() also returns the value of B<a> but it returns 0 if B<a> is
 NULL and -1 on error (which is ambiguous because -1 is a legitimate value for
 an B<ASN1_INTEGER>). New applications should use ASN1_INTEGER_get_int64()
