 A multi-purpose Cryptography library in Java. Working on it day by day, slowly. Someday this will become used, today is not that day.
+
+
+Use `setopt interactivecomments` (zsh only) to disable errors like `zsh: command not found: #`
+Ensure Java + javac are installed, on MacOS it can be installed with Homebrew by running `brew install openjdk`
+
+To compile on MacOS 26 (may work on other OS, idk):
+
+1- mkdir -p out # create output directory
+2- javac -d out $(find src -name "*.java") # converts .java into .class bytecode
+3- jar cfe XACrypto.jar de.caydenno1.xacrypto.XACrypto -C out . # package the .class files into a .jar
+4(optional)- jar tf XACrypto.jar # view the contents of the jarfile
