How to check the Public Key Algorithm used for a given gpg key (ie: RSA vs DSA)

Today I discovered how to validate the Public Key Algorithm that’s used for a given gpg key. Unfortunately, it’s extremely unintuitive & took quite a bit of digging to figure out how. So I’m leaving this here in hopes it helps someone in their future searches.

Eavesdropping Analysis of PGP Metadata

This post attempts to answer the following question: If an evesdropper intercepts a message encrypted with gpg, how much information will they be able to extract from the message without a decryption key?

I will show the unencrypted metadata added to a GPG-encypted message, and I will present commands that can be used to extract . . . → Read More: Eavesdropping Analysis of PGP Metadata

Extend GPG Key Expiration

I came back from my “cross-country bicycle trip”: to discover I could no longer send signed email because my key expired! I’ve also changed colleges from “SPSU”: to “UCF”:, and my old college is expiring my email address, so here’s what I need to do:

Sabayon, KDE, and Evolution

I recently reformatted my hard drive–switching from pure Gentoo to the Sabayon fork. Sabayon did for Gentoo what Ubuntu did for Debian. It’s generally a lot easier to use, but–unlike Ubuntu–it doesn’t sacrifice functionality for ease-of-use.

New GPG Key

I went to send an email the other day and I was halted when I discovered that my key had expired. I can’t believe that I’ve been using GPG for 6 months, but the time had come to generate a new keypair.
