My PGP Key
September 2019 update: I have a new key with transition statement; my somewhat misguided overengineering of 2014-2016 is preserved below for whatever historical value.
Fingerprint: 2599 9E50 95BA 9A2E 1CE6 305E A890 2A7C ACFD 13B0
Note that I use a subkey for signing, as discussed here.
You can use the key to verify my other online identities through this clearsigned file.
