TrustSign turns trust decisions into cryptographic proof. Envelopes collect signatures, attestations certify outcomes, and artifacts package everything for independent verification.
Multi-party envelope lifecycle with ordered signers, document checksums, and orchestrated completion or decline.
Platform-signed proof for verification and consent outcomes. Each attestation includes payload hash, signature, and issuer key reference.
Hash-chained signing events. Every action produces an entry hash linked to the previous, forming an append-only integrity chain.
Active platform keys published at a well-known endpoint. Any third party can verify attestation signatures independently.
Every signing flow follows the same pattern: create, collect, package.
Add documents with SHA-256 checksums and assign signers with roles, ordering, and required signature levels.
Temporal orchestrates signer challenges with configurable timeouts. Signers complete or decline. The workflow handles both.
On completion, a tamper-evident JSON artifact is generated with checksums, chained events, challenge responses, and attestations.
Traditional signing relies on trust and manual tracking. TrustSign produces cryptographic proof that can be independently verified.
Designed for organizations that need auditable, verifiable proof of trust decisions.
Create signing envelopes with multiple signers, ordered roles, and document integrity checks. Track status from draft to completion.
ECDSA P-256 platform keys with rotation and compromise handling. Active keys published for independent verification.
JSON artifact packages with document checksums, challenge responses, signing keys, and chained events. Integrity-checked on download.
Temporal-backed envelope workflows with signer signals, configurable timeouts, decline handling, and automatic expiry.
