GM Nostr! Had created a new nsec to post this, but thought I'd post on my old account also... Learned of a tragedy this week--a very kind and well respected banjo maker Arthur Hatfield had a fire in his shop, which destroyed it. A friend of his set up a go fund me account, and I wanted to share that URL here for anyone wishing to help: https://gofund.me/365470b2 You can read more on banjohangout.org: https://www.banjohangout.org/topic/401345 Always breaks my heart to see things like this...especially for an artisan such as Arthur that brought joy to so many from his banjos. Thanks all for reading, Prayers I'm sure are also appreciated even in lieu of a donation. #coffechain
GM Nostr! Happy last day of 2024! It's time for me to retire this nsec (mainly for privacy reasons) and take a step back from social media (mainly to try and live a quiet life as Fr. Mike would say). Thank you to all the friends I've made here on Nostr--it's a great community and a great group of folks. Perhaps at some point, I'll create a new nsec and return--but if so, I'll be more of a "reader" than a "poster". But for now, I'll simply close out this year wishing eveyone the best for the future. Devs--keep it going--you've got something truly special here in Nostr--don't ever let anyone convince you otherwise! 😃 God bless you all! Now--it's time for a coffee! (And of course a special thanks to all of you on the #coffeechain)
How to securely and privately timestamp any file using email and SHA256... a) Hash a SHA256 on your file (if you have multiple files, zip them first and then hash the zip file). Windows: certutil -hashfile "file_name" SHA256 Linux: shasum -a 256 <file_name> b) Save the result in a text file (.txt) - identify it with the original file name so you know which file generated the hash. c) Copy the SHA result and paste it in the body of an email (you don't need to include the text file). d) Email the message to yourself. e) Save the .txt file with the SHA with the original file for your records. f) Save the email (don't delete it) so you can check the timestamp if needed in the future. Explanation: a) The SHA proves that the file exists (i.e. there's no way to generate the SHA "after the fact"). b) Sending the SHA via email provides a valid timestamp. c) No private information is sent over email (a SHA hash is worthless series of numbers and letters). d) No third party is needed (while there are some good online services and/or paid services that provide timestamps, you don't have to trust any of these services with your data, and you don't have to worry that a third party provider may not still be around in the future). e) You can run a new SHA on the file at any time in the future to prove the file has been unchanged since the time the original SHA was generated. Definitely took me some extra coffee to figure this out 😃 #coffeechain #asknostrd
