+To encrypt an applet run:
+<code>
+r0ket/firmware$ ../tools/crypto/xxtea loadable/spaceinvaders.bin -e -o loadable/space.c0d -v -k 0012345600000000000000000023456700
+</code>
+Don't forget to change the key to the correct value.
+To sign an applet run:
+<code>
+r0ket/firmware$ ../tools/crypto/xxtea loadable/blsign.bin -s  -v -k 0012345600000000000000000023456700
+</code>
+Make sure the keys used for signing and encryption differ.
+Encryption is optional, but we will require applets to be signed at camp when running a firmware with openbeacon keys.
