Learn about our

Cryptographic & Authentication processes

All documents signed via YumiSign in ‘Advanced Signature Mode’ (i.e. handwritten signature) are time-stamped and cryptographically sealed after completion.

Cryptographic Seal

The cryptographic seal ensures a document cannot be altered after its finalization. In practice, the seal allows anyone to verify the authenticity of a document in the long term.

Certificate Authority

To verify a document’s authenticity in Adobe Acrobat Reader or any other PDF reader, you only need to trust the RCDevs Root Certificate Authority.


YumiSign uses physical HSMs (Hardware Cryptographic Modules) to seal user documents, and the HSM signing certificates are renewed regularly by the RCDevs Root Certificate Authority.


Trusting YumiSign document sealing is very simple: Click on Download RCDevs Root Certificate Authority and follow the steps to install the RCDevs Root Certificate Authority in your computer’s trusted certificate list.

Frequently asked

Are e-signatures legally binding?

In the last few years, all businesses have been confronted to the digital era.

The need to sign digitally in this modern world has given electronic signatures the same obligations as handwritten signatures. In fact, any agreement where the parties’ intentions to become bound are clearly stated, is legally binding.

What is eIDAS?

The eIDAS regulation is a European complex set of laws created to establish trust in electronic transactions between individuals, organizations and government entities across European Member States.

It provides a common predictable regulatory environment for electronic identification and trust services, including electronic signatures, seals, time stamps, registered delivery and website authentication.

This begins by creating rules for electronic identification and trust services to simplify and standardize digital IDs and signatures across Europe.
