tl;dr: Please encrypt a file and send it to me together with a (short) description, how I can make it readable for me.
Everyone is talking about encryption and nobody does it. This is a short summary of my initial asumption. Did you ever try to encrypt a file and to send it someone? How did you do it?
This is a fairly simple and basic task which you can present in a beginner’s course:
Assume another person uses a public computer (Internet cafe, library, etc.). You want to send a file to this person and keep the content confidential to other people. Encrypt a file on your computer and send it to the person.
I ask myself how you would do it. Thatswhy I decided to conduct a little experiment: Dear reader, please encrypt a (no so big) file and send it to me (via mail to firstname.lastname@example.org, you can use my PGP key if you like, comment this post or use some other means to contact me). Add some information which to decrypt the file. You have no idea how to do this? I desperately want to know about it. Please write a mail or leave a comment. You tried and failed? I desperately want to know about it. Please write a mail or leave a comment. I would like to know how easy or hard this task is.
I plan to analyse the data on a anonymous basis and will introduce some tools in later posts.
