User: din7
Functions: dump gpg nice ssh

This command will nicely dump a filesystem to STDOUT, compress it, encrypt it with the gpg key of your choice, throttle the the data stream to 60kb/s and finally use ssh to copy the contents to an image on a remote machine.

Change directory (cd) to the directory where all your encrypted files are placed, and then run the command - then you are asked to insert your secret gpg password - ubuntu 8.04

A very simple command to send a signed and encrypted message from the command line using GPG Keys

eval $(sed -n "s/^d[^D]*DB_\([NUPH]\)[ASO].*',[^']*'\([^']*\)'.*/_\1='\2'/p" wp-config.php) && mysqldump --opt --add-drop-table -u$_U -p$_P -h$_H $_N | gpg -er AskApache >`date +%m%d%y-%H%M.$_N.sqls`

The coolest way I've found to backup a wordpress mysql database using encryption, and using local variables created directly from the wp-config.php file so that you don't have to type them- which would allow someone sniffing your terminal or viewing your shell history to see your info.

I use a variation of this for my servers that have hundreds of wordpress installs and databases by using a find command for the wp-config.php file and passing that through xargs to my function.

curl -s http://defekt.nl/~jelle/pubkey.asc | gpg --import

imports a public key from the web. I know this by head.. but useful nevertheless

tar -cf - folder/ | gpg -c > folder.tpg

Functions: gpg tar

gpg's compression is as suitable as gzip's however your backups can now be encrypted.

to extract use:

gpg < folder.tpg | tar -xf -
tr -dc "a-zA-Z0-9-_\$\?" < /dev/urandom | head -c 10 | gpg -e -r medha@nerdish.de > password.gpg

Functions: gpg head tr

Adjust the

head -c

part for password length.

I use filenames like "hans@commandlinefu.com.gpg" and a vim which automatically decrypts files with .gpg suffixes.
