  • Asymetrical encryption solves this, here is my attempt to do an ELI5:

    Adam want’s to send a chat message to Ben, but want to do it securely, so they use a special program on their computers.

    When the Adam’s program first reaches out to Ben’s computer, it asks for an unlocked padlock, this is a padlock that can only be unlocked by Ben’s program.

    Adam’s program takes the padlock and crafts a new special series of padlocks that only Adam’s program can unlock, which it put’s in a box and locks it with Ben’s padlock.

    The box is sent to Ben’s program, the program unlocks the box and creates it’s own special series of padlocks that only Ben’s program can unlock, put them in a box and locks it with Adam’s padlocks.

    The box is then sent to Adam’s program, and is unlocked.

    This now means that Adam’s program can put messages to Ben in a box, lock the box with one of Ben’s special padlocks and send it on it’s way knowing that only Ben can unlock the box and read the message.

    Likewise, Ben can also send messages in boxes locked with Adam’s padlocks and know that only Adam can unlock them and read the message.

    Added to this is the fact that messages from Ben can be verified as having used the special padlocks Adam sent to Ben, as else Adam’s special key wouldn’t fit the padlocks given to Ben.

    In reality the padlocks are keys to lock a message, and the above text describe a secure key exchange.




  • My need for online photo galleries is just to direct friends and family to see them, I don’t store photos in the cloud.

    I used to put up my photos on deviantart, I have had a gallery there for almost two decades, but lately dA has become very slow to navigate, so I built my own site, I didn’t need much, an index page linking to HTML galleries I export from digiKam.

    After a few weeks of learning, designing and testing HTML and CSS, I have a nice index page that is responsive and easy to update and customize (in limited capacity).

    This runs on a normal webhost, and is lightning quick to navigate, the galleries support browsing with the arrow keys, and just works.

    There are three annoying things about it though…

    1. To update a gallery, I need to recreate it in digiKam and upload it manually to the host.

    2. I can’t include notes with the photos.

    3. I have to edit a link in every gallery to make it be able to go back to the index page and not 404…
