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.

About

SahlSign is a cloud-based e-signature and contract workflow platform for Arabic- and English-speaking teams in Saudi Arabia and the GCC. Upload PDFs in either language or both, place signer, name, and date fields, or use AI suggestions. Signers receive secure email links, verify by one-time code, and need no account or app. Signing can be parallel or sequential, with automatic reminders. Completed PDFs carry a PAdES signature and independent RFC 3161 timestamp, plus a bilingual completion certificate with a scannable verification QR code. A hash-chained audit trail records each step. Teams can use bilingual templates, approvals by value in SAR, five team roles, and obligation and renewal tracking. SahlSign supports HR, sales, legal, procurement, and real estate workflows, including employment documents, service agreements, NDAs, purchase orders, and leases, with right-to-left Arabic and English signing.
