Hello, now that the registration deadline is over here comes the list containing the registered participants in the attachment. In case of transfer issues (e.g. MTAs reencoding the text file), the list is also available at https://openpgpkey.baylibre.com/Fei9keem/keysigning-lpcosse26.txt . In reply to Krzysztof's concern about how trustworthy a statement "yesyes, the fingerprint of my certificate on the list that this suspicious guy created is correct" I dropped the two middle nibbles from each fingerprint. So you can support your statement about your fingerprint by providing these two. Please print out the list, fill in the hash sums (which we will verify when we meet), verify your fingerprint and memorize (or write down) the missing nibbles (if you're on the list) and bring the list to the meetings together with a pen and a proof of identity (as most people will probably want to see such a document before certifying your UIDs). If your hand writing is poor, I recommend filling in the hash sum before printing. Note that the start of the SHA256 hash sum is already prefilled, that prefill has to be kept as is when generating the hashes. For people having missed the registration deadline: You can still bring the prepared list and at least benefit partly from the simplification it yields. For getting signatures I recommend bringing paper slips with your UIDs and fingerprint. gpg-key2ps can create such paper slips. It might be sensible to bring a few of those even if you're on the list for those who attend the events without preparation. We'll meet on Tue (2026-10-06) and Thu (2026-10-08) after the scheduled conference events (Tue: ~ 19:50, Thu: ~ 18:30). We will meet outside the conference venue, in case I manage to organise a room, someone at the main exit will know. For the procedure to actually sign the certificates, see https://baylibre.com/blog/pgp-keysigning-2/. A bundle of all certificates on the list is available at https://openpgpkey.baylibre.com/Fei9keem/keysigning-lpcosse26.pgp If questions arise, don't hesitate to ask. Looking forward to see you in Prague! Uwe
