   KEY POINTS
     * Federal investigators say access to encrypted Signal messages
       helped them to charge the leader of the Oath Keepers, an extremist
       far-right militia group, and other defendants in a seditious plot
       on Jan. 6, 2021.
     * Encryption scrambles messages for recipients so that no one else —
       not even the platform itself — can read them.
     * It's not clear how investigators gained access to the messages, but
       encryption has been a point of tension between law enforcement and
       the tech industry for years.
