Secure channels
The web form is suitable only for high-level scoping. Use one of the channels below for anything sensitive — and note that no channel here is authorized for classified, CUI, or export-controlled material.
How to reach Sanctir securely

OpenPGP key
Key publication pending
A hardware-backed OpenPGP key is being provisioned. Until it is published here, use Signal (Sanctir.15) for encrypted communication. Do not transmit sensitive material by unencrypted email.
When published, the key fingerprint will appear on this page and the key will be referenced from /.well-known/security.txt. Verify the fingerprint through a second channel before relying on it.
What not to send
No channel listed on this page is an authorized system for classified national security information, controlled unclassified information subject to a contractual handling requirement, or export-controlled technical data. Encryption is not authorization.
If an engagement requires handling of controlled material, the handling method and authorized environment are established in the engagement agreement before any transfer occurs. Where counsel is involved, privileged material should move through counsel.
Do Not Transmit
- Classified information
- CUI under contractual handling requirements
