This is a follow on question from the answers of these two:
I would like to be able to serialize hardware with an RSA key (1024 bit) and some unique information. This will come to a total of ~140 bytes. This doesn't seem to be a standard thing, so will this cause issues when it comes to production? Can production programmers serialize with any number of bytes, or like that image in the first question, are you limited to some standard number (4 bytes) etc.
