SUMMARY:📝 One-Time Pad Encryption Workshop
DESCRIPTION:Join us for a workshop on one-time pad encryption! We’ll walk you through a technique for sending truly private messages without a computer\, using 6-sided dice to generate random numbers. We’ll use an encoder/decoder sheet that fits on a single sheet of paper and can be recreated from memory. \nYou can find the workshop materials here: Double Dice One-Time Pad Workshop \nRegister:\nRegistration for this event is now closed. Sorry. \nHere's a link to future workshops in this series! \nThis workshop is now full. We'll offer it again soon! \n  \n  \n

SUMMARY:🐧 E-Z Command-Line Encryption with OpenSSL
DESCRIPTION:At this workshop you’ll learn to create passphrase-protected files using OpenSSL\, a command-line program that’s probably already installed on your computer. With this technique you can send encrypted files via email/Dropbox\, then share the passphrase with the recipient on a secure channel (e.g.\, Signal). Useful for avoiding surveillance & data mining! \nSave message:\necho "My secret message ❤️" > example.txt\n\nEncode:\nopenssl aes-256-cbc -a -in example.txt -out message.enc.txt\n\nDecode:\nopenssl aes-256-cbc -d -a -in message.enc.txt -out plain-text.txt\nRegister\nRegistration for this event is now closed. Sorry. \nHere's a link to future workshops in this series! \nThis workshop is now full. We'll offer it again soon! \n  \nPhoto CC-BY-SA Mark Dickson
