<AboutParagraph title="how does it work?">
<span>
each note has a generated <code>id (256bit)</code> and <code>key 256(bit)</code>. The
<code>id</code>
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.
