Elliptic Curve Cryptography in OpenSSH

I've been meaning to add this as a post, as it's light and quick, but as the release of OpenSSH 5.7, Elliptic Curve Cryptography has been implemented. Why should you care? The generated keys are substantially smaller, the algorithm is faster and lighter, giving a break to slower CPUs and the cryptanalysis hasn't shown any […]

GnuPG Up And Close

Every GNU/Linux distribution ships with GnuPG by default. While they all don't ship with the same GUI frontend, they do ship with the the same CLI backend. So, we'll be interfacing with that throughout this informational session. I'm not presenting this as anything necessarily useful. Rather, I hope you find it informational/educational, and learn a […]

Using GnuPGv2

I've moved to GnuPG version 2, mainly just out of curiosity. I have read the feature list between version 1 and 2. Apparently, version 2 supports the same algorithms, completely backwards-compatible with version 1, more modular and supports additional functionality. So, with that, my GPG key has been re-exported using version 2. It's available on […]

Update My Public Key

At your earliest convenience, you'll need to update my public key in your keyring. You can grab the cleaned copy from my site, or your can get an uncleaned copy from either the Ubuntu keyserver or the PGP keyserver. Please do not use the MIT PGP keyserver, until I can get straightened out why they […]

MIT PGP Keyserver

I just discovered, after spending some time trying to get my public key uploaded to the MIT PGP keyserver that they do not support photos in public keys. I find this rather unfortunate, as photos add a level of security to the key. This also means that any IDs that I add to my key […]

GnuPG Turns 10

Happy Birthday to the GnuPG team and community. GnuPG turns 10 today! For those caught unaware, GnuPG was designed to be a Free Software implementation of PGP, removing the patented algorithms, such as RSA and IDEA, and replacing them with Free Software algorithms, such as Blowfish and ElGamal. Being a strong advocate of GnuPG and […]

A Perfect Reason Why You Should Digitally Sign Emails

According to a supposed email from lead developer of PHP Jani Taskinen, he's outta here, and not looking back. Goodbye PHP, goodbye cruel world! is the theme of his email. From: Jani Taskinen Subject: Good bye. Group: php.internals Date: Thu Jul 27 20:28:45 2006 Thank you all for the last 6 years or so. It […]

Public Keyservers

As mentioned in my last post, I don't generally use keyservers. I would much rather just email the key or leave it posted on my blog. However, with that said, I do have my key published to the 3 most popular keyservers on the web, with the first as my default in both Seahorse and […]

My GnuPG Public Key

For those of you who read my blog and wonder if I have a GPG key, well your in luck! I have had a key since Glen, a friend of mine, introduced me the world of encryption and security in September 2004, and my life hasn't been the same since. I used to sign all […]
