DER encoding IS fully reversible.
However you're right about some certificate, that have been improperly signed
when they were not valid DER.
Hopefully this is a thing of the past, and I do intent to keep re-encoding the
certificate instead of passing a binary blob (as i used to do at first, with
some vestigial code still present). It gives a good workout to the certificate
and asn1 DER modules as well, which isn't all that bad.
