Obfuscate some data in perl

If you have some data you don't want to be readily readable in Perl you can obfuscate it with the unpack function. You can take a given string and encode it as printable hex and store that, and later unpack it for use in the real world.

perl -e "print unpack('H*','print \"I love perl\!\n\"');"
perl -e "eval pack('H*','7072696e74202249206c6f7665207065726c5c215c6e22');"
