swaylock-ecb

Swaylock with multi monitor support and AES-ECB image encryption

General

Inspired by i3lock-fancy-multimonitor and swaylock-fancy.

• For every connected monitor, a screenshot is taken using grim.
• The screenshot is then encrypted using python in AEC-ECB mode.
• The resulting encrypted image is pixelated using imagemagick and a lock icon is added.
• The image files are quite large (several megabytes), but this is the fastest way to process images.
• The temporary files are deleted after swaylock detaches.
• Unencrypted screenshots are stored in memory for a brief time, but never on the filesystem.
• Image files are stored in the temporary directory. On most modern Linux systems, this should be a ramdisk.
