 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.

## Verify a signature

 You can verify signed messages and files directly in your browser. Verification is performed locally. The message or file you select is not uploaded to this website.

### Signed message

 Paste an ASCII-armoured clear-signed OpenPGP message below.

### File signature

 To verify a detached signature, select both the original file and its `.asc` or `.sig` signature.

## Verifying manually

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

```
FE67 3AD7 59DC 01A2 64DC 933F D4B4 2566 BB8B 28FA
``` 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 certificate.

## Encrypted messages

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