About

Qausal is a web-based electronic-signature platform for preparing and verifying signed PDF documents. Users can upload a PDF, invite one or more signers, assign signing roles and sequence, and track signature progress; invitees can sign without creating an account. Qausal uses ML-DSA-65, the post-quantum digital-signature algorithm standardized as FIPS 204, to create signatures intended to remain verifiable against future quantum-computing risks. Signature data, public keys, and digests are embedded in the signed PDF, and users can download a proof bundle for independent offline verification with open-source tools. Qausal also supports adding a quantum-safe attestation to documents signed through other services without altering the original document. It is intended for organizations that need durable verification of agreements and records, including legal, financial, healthcare, and government-related workflows.
