What: Certificate Transparency
Where: 1930 SW 4th Avenue, Portland, Oregon 97201-5304, Room 86-01
When: Thursday, February 5, 2026 at 7 PM
Why: The pursuit of technology freedom
Summary:
A few things like the recent update to the Certificate Transparency
ecosystem to allow the “static CT API”, which is much cheaper to
operate; and the new IETF working group PLANTS for Merkle Tree
Certificates and why it’s relevant to Post-Quantum cryptography. I’ll
provide an intro about what Certificate Transparency is.

PLUG is back at Portland State University, thanks to the Computer
Science Department and to Andrew Greenberg. The room is in the basement
of the PSU Engineering Building (also connected underground to the
Fourth Avenue Building, or FAB). Enter through the Engineering Building.
The outside door will be locked, but there should be someone present at
the entrance to let you in starting at 6:40pm until 7pm. There will be a
sign on the door with a phone number you can SMS if there isn't someone
there to let you in immediately.
