Gotta get some sleep, but been doing some digging.

I'm wondering if the BRIDGE is the Federal Bridge Authority. Here's some resources if any resourceful anons want to dig on this until I can get back to it after some sleep.

The Federal Bridge Certification Authority (Federal Bridge) today cross-certified with the public key infrastructures (PKI) of the U.S. Department of Defense, U.S. Department of the Treasury, U.S. Department of Agriculture National Finance Center, and National Aeronautics and Space Administration, allowing them to trust and validate the digital signatures on files issued and received by each other.
