About

PQC Imza is a web-based electronic-signature service that applies ML-DSA-44 (NIST FIPS 204) post-quantum signatures to documents. Senders upload PDFs or prepare documents using templates and an AI-assisted builder, then invite signers and decide which completed signatures to accept. Signers use the PQC Wallet mobile app to verify identity with the NFC chip in an ID card or passport and sign on their phones. The resulting PDF lists signers on each page and includes a QR code for later verification; the document fingerprint and signature records are anchored on SciChain. Customers can buy per-document credits, non-expiring credit packs, or monthly and annual plans; invited signers sign at no charge. The service is designed for individuals and organizations collecting electronic signatures. In Türkiye, these signatures are not qualified secure electronic signatures under Law No. 5070.

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.
