This paper examines the challenges and future of digital signatures, which are widespread today, and the electronic signatures based on them. Several electronic signature schemes have been defined worldwide; the European version is governed by the eIDAS Regulation. Electronic signatures based on public key cryptography currently in use will be compromised by high-performance quantum computers. In my article, the basic operation of electronic signatures is presented, and vulnerable points are identified. I shall furthermore cover the various recommendations to help the transition to the post-quantum era, NIST, ENISA, etc., which provide guidance on how to strengthen systems that are still operating in production environments against quantum attacks as long as standardized, quantum-safe public-key cryptographic primitives are on the way.
