What is Qausal?
Qausal is an electronic signature service hosted in the cloud, enabling users to create and authenticate signed PDF documents efficiently. The platform allows individuals to upload PDFs, invite numerous signers, assign specific roles for signing, and track the signing process, all while permitting signers to participate without needing to register for an account. Utilizing the ML-DSA-65 post-quantum digital signature algorithm, which is acknowledged as FIPS 204, Qausal ensures that signatures remain valid even amid future advancements in quantum computing. Each signed PDF contains signature data, public keys, and hashes, and users can also request a proof bundle for verification using open-source tools. Additionally, Qausal supports the integration of quantum-safe attestation for documents signed on other platforms, maintaining the integrity of the original document. This solution is especially advantageous for businesses that need trustworthy verification of contracts and records, including those operating in the legal, financial, healthcare, and governmental fields. By offering these capabilities, Qausal helps users streamline their document workflows while safeguarding their agreements against the challenges posed by advancing technology, ultimately promoting confidence in digital transactions.
