eIDAS (electronic Identification, Authentication, and trust Services) is an EU regulation on electronic identification and trust services for electronic transactions in the European Union. It was established in EU Regulation 910/2014 of 23 July 2014 and applies from 1 July 2016. This regulation is a guiding torch that provides detailed conditions and differentiation related to three different types of electronic signatures: simple, advanced, and qualified.

Basic or Simple Electronic Signatures

The digital certificate could also be a secure, personal and unique electronic identity credential that possesses to be issued to the signer to keep under their control.
Qualified electronic signature must comply to the requirements of both electronic signatures and advanced electronic signatures, and also be:
A qualified e-signature reverses the burden of proof that generally is created during a digital transaction. With qualified e-signature, the signer must produce the digital certificate used to authenticate the signature.
Legal validity of electronic signatures under eIDAS
eIDAS ensures that each kind of electronic signature has legal validity and admissibility as evidence in EU courts and shall not be denied legal effect solely because of its electronic form.
