GPG for your Mac

Talking to peers over email is a unsecure (for the paranoid in me). It's nice to try something that can make the badguys work a bit harder. Enter... GPG!

GPG (Gnu PGP) is a good way of encrypting and verifying that the data really belongs to the said person, and here's how i did it on my mac.

Install GPG

http://www.gpgtools.org/installer.html

From the shell[Terminal]. ($)

Tip 1.) To Generate your own GPG Key (Follow the instructions after running the command below. Keep the Default DSA Elgamal Encryption) and viola! you have your own gpg key.

$gpg --gen-key

Tip 2.) To Verify your key

$gpg --list-secret-keys

Tip 3.) Exporting your GPG Key (good for Emails)

$gpg --output MyGPGKey.pgp --export john@doe.email

Tip 4.) Exporting your GPG Key (for Public Display website, etc.)

$gpg --output MyGPGKey.pgp --export john@doe.email --armor

Tip 5.) Importing someone else's GPG Key (Extensions sometimes come as .asc or .gpg)

$gpg --import foobar.asc

Tip 6.) To Validate GPG Keys from others

$gpg --edit-key john@doe.email

Tip 7.) To send your key to a public GPG Server (GPG ID is found on the sec portion of the output for Tip #2)

$gpg --send-keys GPG ID

Keep safe on the Internet

In-line Image Go Away.

I really hate the way mac os x mail does inline attachments.
Why can they just leave the attachments alone....

after googling i found a way to make this go away and behave like any good old attachment.

To Disable In-line attachments on Mail.app [AppleKey + Shift + U --> select Terminal.app] with this command:

defaults write com.apple.mail DisableInlineAttachmentViewing -bool yes

If you want to make your email look default butt ugly you can restore it on Mail.app [AppleKey + Shift + U --> select Terminal.app] with this command:

defaults write com.apple.mail DisableInlineAttachmentViewing -bool false


whew! :) Better!
