+			each note has a generated <code>id (256bit)</code> and <code>key 256(bit)</code>. The

+			is used to save & retrieve the note. the note is then encrypted with aes in gcm mode on the client
+			side with the <code>key</code> and then sent to the server. data is stored in memory and never
+			persisted to disk. the server never sees the encryption key and cannot decrypt the contents of
+			the notes even if it tried to.
