OpenSSL Encryption Fun

posted

I re-discovered the fun that is OpenSSL's encryption today when I was cleaning up some bash aliases and though I'd share them.

This allows you to do some really stupid but fun things like encrypt backups, or messages to pass to a buddy. The uses are endless!

File: bash_aliases.sh --------------------- # Put this somehwere in .bashrc/aliases/etc. # OpenSSL must be installed -- these are just aliases. alias enc='openssl enc -e -aes-256-cbc -salt ' alias dec='openssl enc -d -aes-256-cbc ' File: usage_fun.sh ------------------ # encrypted gzipped db dump mysqldump -uroot DBNAME|enc|gzip -c>db.sql.enc.gz # decrypted gzipped db dump gunzip -dc db.sql.enc.gz|dec>db.sql # decrypted gzipped db dump to import -- sneaky sneaky o_O gunzip -dc db.sql.enc.gz|dec|mysql -uroot DBNAME # encrypted tarball tar czf - blah/|enc > blah.tar.gz.enc # decrypt encrypted tarball dec < blah.tar.gz.enc|tar xzf - # fun with passwords! enc < passwords.txt > passwords.txt.enc dec < passwords.txt.enc > passwords.txt # ... and so on and so forth ...
