In it I cut my teeth on using an FPGA to interface with target hardware. After implementing a UART we implemented a module that could parse part of Apple’s OneWire, used to negotiate…
As well as the collection and distribution of compromised keys , the pwnedkeys project also matches those pwned keys against issued SSL certificates. I’m excited to announce that, as of the beginning of 2024, all matched certificates are now being published on the Fediverse , thanks to the botsin.space Mastodon server.
