Linux Lab: E-Z Command-Line Encryption

The first Sunday of every month we’ll host a self-guided tutorial for Linux beginners.

On March 2nd we’ll focus on no-frills encryption techniques using the command line. Stop by any time from 10:30 a.m. to 12:30 p.m. and learn a new skill! We have plenty of computers to share.

We’re suggesting a $5–$10 donation for this one, no one turned away for lack of funds.

echo "My secret message " > example.txt

openssl aes-256-cbc -a -in example.txt -out message.enc.txt

openssl aes-256-cbc -d -a -in message.enc.txt -out plain-text.txt
