Description

X.509 Certificate

variable

(length encoded in X.509)

DER encoded X.509v3 Certificate.

The length can be parsed from the first

TLV sequence which spans over the

complete certificate.

Zero padding

variable

(remaining bytes up to the complete

binary file size)

The file size of the binary file is constant

over all devices of a type, while the

specific device certificate can vary

in size per device (due to the ASN.1

encoding of numbers).
