What is sproof sign?

sproof is a European platform for digital trust, signature, and identity processes.

What is PQC Imza?

PQC Imza provides an online electronic-signature solution that utilizes ML-DSA-44 (NIST FIPS 204) post-quantum signatures for managing documents. With this platform, users can either upload their PDFs or create new documents from templates and an AI-driven builder, after which they can invite signers and decide which signatures to confirm. Signers are able to verify their identities via the PQC Wallet mobile application, which uses the NFC capabilities of their ID cards or passports, allowing them to sign documents effortlessly on their mobile devices. Each generated PDF includes detailed information about the signers on every page, incorporates a QR code for easy verification, and ensures the security of the document's fingerprint and signature records through SciChain. Customers can purchase credits on a per-document basis, choose from non-expiring credit bundles, or opt for various subscription options that are available on a monthly or annual basis, all while allowing those invited to sign at no charge. This service is designed to accommodate both individuals and organizations looking for an efficient way to collect electronic signatures. Nevertheless, users should be aware that in Türkiye, these electronic signatures do not qualify as qualified secure electronic signatures according to Law No. 5070, emphasizing the importance of understanding local legal frameworks. Understanding the nuances of these laws can help users navigate the electronic signature landscape more effectively.
