Most of you probably use netcat for your shells. I don't discredit that one bit because that's how I started too. But netcat isn't capable of giving you encryption which is where OpenSSL comes in. In a defended network where you don't have file transfer capabilities, you need to LOTL again (Live/Living off the land) that's why one solution is to use openssl alongside mkfifo which are both Linux binaries that come installed.
