OpenPGP – PrivaSecTech https://privasectech.com/ Wed, 13 Nov 2019 18:33:33 +0000 en-US hourly 1 https://wordpress.org/?v=5.4.2 GNU Privacy Guard https://privasectech.com/gnu-privacy-guard/ Mon, 02 Jul 2012 19:50:47 +0000 http://privasectech.com/?p=276 Continue reading GNU Privacy Guard]]> Ever since PGP removed their open source client, GnuPG has been the standard in open source PKI. If you want to encrypt your emails and/or files on your computer, you’ll need this installed, and a basic understanding of how it works. One of my next posts will be talking about an amazing privacy tool that requires gpg, so give it a try, you’ll never know when it will come in handy.

Late last night for example, I had to sign a non-disclosure agreement (NDA) with a lawyer, with no access to a scanner or printer. I was able to do this easily with gpg.

Anyway, if you want to give it a try, follow these steps (It will work best if you have a friend to try it with!):

  • Download a GnuPG (gpg) and give a try. (scroll down to binaries and find your operating system)
  • Generate an initial keypair; a private key and a public key. If anyone else ever gets access to your private key, the whole exercise is useless, so protect it by all means necessary! At the same time, provide a copy of your public key to anyone you wish to communicate with. You should look for the ASCII encoding option when extracting your public key, so the filename ends with .asc.
  • Add your friend’s public key to your public keyring
  • Create a sample text file or email, and encrypt it using gpg
If you get stuck with the steps above, which I’ve overly simplified, you get a lot more detail with the HOW-TOs and guides. Once you’ve got the basics down, set yourself up with email encryption.
Feel free to send an encrypted email to kris@privasectech.com (link is to my public key) to test it out. Make sure you also attach your public key in an ASCII encoded format (filename.asc)!

Email Encryption https://privasectech.com/email-encryption/ https://privasectech.com/email-encryption/#respond Sat, 09 Jan 2010 06:49:21 +0000 http://privasectech.com/?p=8 Continue reading Email Encryption]]> On our contact us page we mention OpenPGP standard encryption (RFC 4880). What is this? Most people think email only goes to the intended recipient, but instead it travels across the internet like a postcard. Even if you’re emailing your neighbour, that email postcard will often cross international boundaries. Once that postcard goes out, you have no control of where it goes, or how long it stays out there.
For those that prefer to send their mail in an envelope, email encryption offers this. There are several solutions available you can use to communicate with us, your business partners, friends and family. They will all likely require GnuPG Open source (free)

  • enigmail Open source, works with Mozilla’s Thunderbird (free)
  • kPGP Open source (free)
  • Seahorse Open source (free)
  • MacPGP Open source for MacOSX (free)
  • PGP Commercial for Windows or MacOSX ($$$)
