Always verify the fingerprint before using the key for sensitive communication.
Contact
Contact and Key Verification.
For most contact, email me at mail@steadytao.com . Encrypted email is preferred. Signal is available as a secondary encrypted channel. This page sets out the preferred lane, verification details and what context is useful up front.
Preferred contact
Email is the primary channel.
Use this address for general contact, technical discussion and anything non-urgent. Encrypted email is preferred when appropriate.
Secondary
Better for more immediate or conversational contact, still treated as a secondary channel rather than the default.
OpenPGP
Key discovery and verification.
My public key is available directly from this site via WKD and from keys.openpgp.org.
If you have never used OpenPGP before, the practical flow is
simple: get my public key, verify the fingerprint, then use that
key to encrypt mail to mail@steadytao.com.
As per OpenPGP Web Key Directory; on GnuPG, this will try WKD automatically and fall back to other clear sources:
gpg --auto-key-locate clear,wkd --locate-keys mail@steadytao.comIf you want an encrypted reply, include your public key with your message or ensure it is discoverable from your address.
Which channel to use
Choose the channel that matches the message.
Use email for most contact, technical discussion, longer messages and anything requiring attachments or a durable record.
Encrypted email
Use OpenPGP when the message is private or security-sensitive.
Signal
Use Signal for more urgent or conversational contact where email is unnecessarily heavy.
Notes
A little context helps.
I prefer clear subject lines and concise context.
Encrypted email is welcome when appropriate.
I may not respond immediately, especially to vague outreach.
For project-specific matters, include relevant links or context up front.
Security disclosures
If you are contacting me about a security issue in something I maintain, use encrypted email where possible and include enough detail to reproduce or understand the issue.
