 I use OpenPGP to cryptographically sign files, messages, software, security research, and other material that I publish. You can use the public key below to verify that signed material came from me and has not been modified since it was signed.

## Verifying my signatures

 When verifying something I have signed, check that the signing key has the following full fingerprint:

```
22F0 F917 E4D8 96B9 48EE 359A 6E35 29B1 9445 A573
``` Do not rely only on the shorter Key ID when establishing the identity of the signing key. The full fingerprint above is the canonical identifier for my OpenPGP key.

## Encrypted messages

 You may also use this public key to encrypt information intended for me. Please verify the fingerprint above before using the key for sensitive communications.
