One-time pads provide perfect security for the message itself (if they are handled properly), but adversaries can still tell that messages are being sent, and when they are being sent. To avoid this, dummy messages are uploaded to a website on a regular basis. The messages can also be hidden using steganography.

+This application should not be considered secure, and no sensitive information should be entered into it.
-
+
-Baseline is that the number station will generate a dummy random message, optionally obscure it via steganography, then upload it to an (s)ftp/scp server.
+# Building
-
+
-The random message generation actually happens last, so that, next time it is run, the existing message will be uploaded. This way a real message can be generated in the meantime and the next upload time the real message will be uploaded. Because the real message looks random to anyone without the corresponding one-time pad, it cannot be distinguished from the dummy messages.
+Building requires JDK 23.0.1 and javafx SDK 23.0.1, and Maven (I used version 3.9.9)
-
+
-# Number Station Listener
+The JAVA_HOME environment variable must be set to the JDK installation directory e.g. `C:\Program Files\Java\jdk-23.0.1\bin\java.exe`. `$JAVA_HOME/bin` must be included in you PATH variable. PATH_TO_FX must be set to the JavaFX lib directory e.g. `$HOME/openjfx-23.0.1_windows-x64_bin-sdk/javafx-sdk-23.0.1/lib`.
-
+
-This application periodically checks a site for numbers and stores them so the user can check whether the message matches any pads.
+To build, run `mvn package`, the output .jar should be in ./target
-
+
-# Notes
+To run without installing: `java -jar target/numbersstation-1.0-SNAPSHOT-shaded.jar`
-
+
-Should have sane defaults, but be built to be part of a more extensible system. Should be able to run other commands for message generation / upload.
+# Packaging
-
+
-Need to be able to support multiple profiles for each.
+Packaging is done via jpackage, which is included with the JDK version used to build.
-
+
-## Tech
+jpackage seems to pull in the entire working directory unnecessarily. To avoid bloat, packaging should be done in a clean subdirectory.

-This weakness is true of nearly all communication methods though. The only way to be certain a message was received is to receive an acknowledgement back.
