stunnel4 3:5.68-1 (riscv64 binary) in ubuntu lunar

 The stunnel program is designed to work as SSL encryption
 wrapper between remote client and local (inetd-startable) or
 remote server. The concept is that having non-SSL aware daemons
 running on your system you can easily setup them to
 communicate with clients over secure SSL channel.
 .
 stunnel can be used to add SSL functionality to commonly
 used inetd daemons like POP-2, POP-3 and IMAP servers
 without any changes in the programs' code.
 .
 This package contains a wrapper script for compatibility with stunnel 3.x
