Every email from us is signed with our OpenPGP key, which also travels in its Autocrypt header. Use this key to write to us encrypted:

PGP Publickey: 0x2185CC8F3CA782EC or on keys.openpgp.org

PGP Fingerprint: 5FA5 2398 C382 B498 B14A B7F6 2185 CC8F 3CA7 82EC

Encrypted replies

We reply encrypted automatically once we have your key and trust it. For that, sign your email to us. We take your key from the email (attached or in its Autocrypt header) or from keys.openpgp.org, and use it by ourselves if

• keys.openpgp.org hands it out for your address (so your address is verified there), or
• your email carries a valid DKIM signature from your sender domain.

Otherwise someone on our team confirms it by hand first. From then on, everything we send you is encrypted, not just replies.

We trust the first key we receive this way for your address (trust on first use). We don't switch to a new key for the same address automatically: until we have checked it, we keep encrypting to the previous one.

We never answer an encrypted email unencrypted. If we don't have your key, we can't reply, so please always sign encrypted emails to us.
