Verify copied words

Paste a post (its text plus the ↳ proof line) to check the exact words against the cryptographic proof. Use a post's Verify button to load it here.

The post you create is signed live at the software tier (a real P-256 signature). The example posts above illustrate the higher tiers; reaching vTPM, hardware, or device-attested requires a TPM 2.0 or Secure Enclave device. Open any ↳ proof link to see its full provenance score. Labels above software are claims until backed by hardware attestation, which is exactly why they score higher.
