KeyFlux Sign
Sign Documents with
Verified Identity
Credential-verified document signing powered by verifiable credentials. No passwords. No accounts. Just cryptographic proof.
How It Works
KeyFlux Sign replaces passwords and email verification with cryptographically verifiable credentials from your digital wallet.
Credential Verification
Check signer identity using verifiable credentials presented from a digital wallet, including issuer and device-key validation.
PDF Approval Evidence
Embed a KeyFlux platform signature and signer approval evidence in the PDF, then verify the document independently from the Sign registry.
Audit Trail
Record timestamped events that link the signing journey, identity checks, signer approval, and resulting document.
