Sovereign mail · Cyph.27 identity

Share without the leak

Pass plans, credentials, deal docs, and ops notes — knowing the mailbox isn’t a reading room for Google or Microsoft. Your address is also a Cyph key.

Why it exists

Sensitive work needs a closed channel

Founders, crews, and operators move information that shouldn’t sit in a consumer inbox. Nullxre Mail is the enclave for that — email you actually own, keyed to Cyph, so people and teams can share valuable info without worrying about the usual leaks.

Founders Term sheets, cap tables, investor threads — off the big-tech mailbox.

Crews Credentials handoff, deploy notes, vendor secrets between trusted people.

Operators Deal docs, ops runbooks, incident detail — shared on your terms.

Teams Trust via Cyph buddies + the mail enclave — not “another Gmail.”

Encryption stack

How the lock works

E2EE

End-to-end encryption on secure transmissions — content stays between endpoints, not open for casual inspection on the wire.

Cyph keys

Every @nullxre.com address mints a Cyph.27 identity — same login for mail and the key graph. Friends chat lives inside Nullxre Mail; open full Cyph when you need rooms and groups.

256-bit

256-bit encryption on the secure channel — serious crypto, not a marketing checkbox.

Sovereign

Proprietary protocols for the mesh — Cyph messaging and the mail enclave under one sovereign stack, not a white-label of someone else’s cloud mail.

Operators: secure mail transmissions use Cyph-ECDH-AESGCM-style key agreement and authenticated encryption inside the Nullxre mail enclave — identity tied to your Cyph key, not a rented inbox.
