In my first video on writing SFTP clients in Java I used a library called jsch. jsch does what it claims but it does feel a little bit dated. The Java library that I’m going to show today is called sshj (https://github.com/hierynomus/sshj) and it has a much more modern feel to it.

Advantages of using sshj over jsch:
Supports "BEGIN OPENSSH PRIVATE KEY" style private keys out of the box
Uses the Java collections framework e.g. java.util.List instead of java.util.Vector
Updated more frequently
