PGP Key Canary

The following file is a canary file (i.e. "warrant canary")
which demonstrates my continued ownership and possession of my
PGP keys. This file is signed with my PGP key and updated on a
regular basis. You may find my PGP public key at: /pgp.txt

I am the admin of Shen's Essays.
I am in control of my PGP key.
I will update this canary within 14 days.
Today is 2022-08-01.

Be aware that on May 6th, 2022, I updated my PGP *public key*.
This was because I added some additional userids (i.e. emails)
to my existing key. The PGP key itself *has not changed*. Only
the public key has been updated/regenerated. You may fetch the
latest version of my PGP public key at /pgp.txt as always. You
can check that my PGP key has not changed by verifying this
signed canary with both my old public key, and my current public
key. Both keys will verify correctly for the same signature.
