Keys of Steffen Prince (sprin) <steffen@sprin.io>

I use tools based on the OpenPGP standard to encrypt private messages and sign documents, code, public messages.

The Master Key

All my keys are signed by the following Master Signing Key:

pub   4096R/3006E021 2016-07-05
      Key fingerprint = D0A6 F47A 49D6 7A7D 0369  4BE0 A587 D405 3006 E021
uid                  Steffen Prince (Master Signing Key) <steffen@sprin.io>

You should verify the fingerprint of this master key using some other channel than just this repo (e.g. my Hacker News account or from keys.sprin.io as in case somebody was providing you with a falsified repo, they would be sure to also feed you with a falsified master key.

The key is attached here: sprin-master-key.asc.
