lsh-utils 2.1-10 (arm64 binary) in ubuntu zesty

 lsh is a GPLed implementation of the Secure SHell protocol version 2
 (SSH2), a secure replacement for rlogin, rsh, and rcp.
 .
 This package contains the lsh utilities. This includes programs such
 as lsh-keygen, lsh-writekey (both programs for public/private key
 generation), lsh-authorize (for automatic remote key authentication),
 ssh-conv (utilities for converting between various public and private
 key formats), and a number of other utilities for use with both the
 lsh server and client.

 In some countries it may be illegal to use any encryption at all
 without a special permit.
