The things one runs across sometimes.

I keep wishing I could run across my old directory of domain administrators from the late '80s. A paper book (I was in it). From bbn I think. I think that got lost several office moves ago unfortunately.

Haha, I recognized that on Dec 1 2024, I will be an #InfoSec professional for 25 years.

I had almost any kind of possible job in InfoSec, but my heart still beats for low-level technical stuff.

As mentioned already, my first graduate project was to contribute to an implementation of PCT (Protecting Content Type), a signature scheme for #X400 messages in the late 1990s.

@emilis the latter...

#eMail timeouts are in the magnitude of hours if not days, but even the worst #API|s will timeout within 15mins of not a few seconds.

And faster comms like #X400 & #AS2 never caught traction outside nieches where security and traceability of communication paths was more important..

#ISO #X400 #MHS (Message Handling System). What an anachronism.

1999-2000, we implemented the #PCT (Protected Content Type) Standard that was basically equivalent to integrity protection an digital signatures w/ X.509 certificates in S/MIME.
