Semiprivate Keys

🚨 DANGER: INSECURE! 🚨

This may have seemed like a great idea in 2013, but the repeated "set/clear bits", a.k.a. clamping phases at each level of the hierarchy slowly subtract key strength.

Don't use this as described. Check out Ristretto.

Here are two tours of San Francisco and the surrounding area. Both take about a day. One is entirely within the city and can be done entirely via public transportation. The other requires a car and gets you outside of SF to some of the wonderful sites that comprise the Yay Area.

San Francisco by Foot

  • You can start anywhere in the Castro, Mission (home of the burrito), or downtown. I'd recommend starting at Chow at Market & Church or The Pork Store on 16th at Valencia. If you wanted to go upscale on the weekend, Maverick at 17th and Mission is a fantastic brunch. Another option is to start in Chinatown (just north of Union Squre) for dim sum.
  • From Castro take one of the N, J, etc. trains (every light rail train route in the city intersects at Church and Market) down to the Powell Street station. From the Mission you can take BART a couple of stops up to Powell Street.
  • Once at Powell Street hop on the Powell Street trolley. A quintessential SF experience.
  • Take the trolley up through the city where it will eventually stop at Lombard Street, which is known as the most crooked street in the world. Walk down the hill, take a few pictures and laugh at the tourists trying to drive down the damn thing.
  • Once at the bottom of the hill, turn left. You'll be walking towards the w

Most VPN Services are Terrible

Short version: I strongly do not recommend using any of these providers. You are, of course, free to use whatever you like. My TL;DR advice: Roll your own and use Algo or Streisand. For messaging & voice, use Signal. For increased anonymity, use Tor for desktop (though recognize that doing so may actually put you at greater risk), and Onion Browser for mobile.

This mini-rant came on the heels of an interesting twitter discussion: https://twitter.com/kennwhite/status/591074055018582016

HOWTO: Twitter DM with OTR

Twitter DM + OTR: A quick and dirty tutorial

With the recent removal of the 140-character limit in Direct Messages by Twitter, DM's have now become a much more useful platform for communicating between individuals and groups. Sadly, DM's are still sent in plaintext between users and Twitter has no plans currently on encrypting these messages, at least as of August 2015. Since these are stored in plaintext at rest, an adversary can see the content of the message you are sending, which the two parties might not wish to happen. Fortunately as a few applications with basic Twitter support which also have excellent support for OTR, all hope isn't lo
