Definition of Electronic Signature in 5 Points

What is an electronic signature? It is a signature made electronically using information and verification systems, such as cryptography, to certify the digital identity of the signatory, known as the "author".

This digital signature has the legal value and is now replaced by the signature handwriting, which in many cases is likely to be discontinued.

Criteria 1: Main Characteristics

To reflect the same legal value as a handwritten signature, an online electronic signature must meet the following conditions:

  • The signatory must have an electronic certificate authenticating their identity.
  • The digital signature procedure must be secure and certified as compliant.
  • The signature is final, the signatory can not argue it.
  • The document to be signed must be original, unalterable and not editable for example a pdf.
  • Signed documents must be kept in a secure electronic safe for 10 years.

Examples of electronic signatures:

Types of documents

There are different types of documents to be signed electronically:

  • Invoices
  • Payslips,
  • emails,
  • Commercial contracts,
  • Supplier contracts,
  • Letters,
  • Internal memos,
  • Validation messages,
  • HR processes,
  • Quotes,
  • Purchase orders, etc.


There are different file formats for signed documents, including:

  • Word format,
  • PDF format,
  • XML format,
  • Image format such as JPG or PNG, etc.

Application examples :

  • The most common and recommended file format for contracts is PDF because it is not editable and can be signed electronically.
  • Both public institutions and local authorities also use XML files.

The eIDAS (Electronic Identification and Trust Services) regulation, which came into force on July 1, 2016, defines a framework and strict standards for electronic commerce and aims to harmonize practices at the European level.

Through secure electronic exchanges, the objective is to build trust between individuals, businesses and public administrations. The legal electronic signature procedure is thus linked to an electronic identification.

This electronic identification, called an electronic signature certificate is issued and guaranteed by companies called trusted third parties. These companies themselves obtain certifications before becoming trusted third parties. Certifications for trusted third parties are issued by recognised bodies such as ETSI, the European Telecommunications Standards Institute, as well as other parties that exist at a national level (e.g.: ANSSI in France).

To become a trusted third party, a company must, among other things:

  • Comply with the security and confidentiality obligations defined by the eIDAS Regulation,
  • Apply the RGS repository to be compliant (signature encryption, cryptography, etc.),
  • Obtain the mandatory certifications from recognized organisations,
  • Obtain a trust label, defining a transparency framework, etc.

Criteria 3: Trusted Third Party and Electronic Signature Certificate

As we have just seen, to guarantee and certify the integrity of a digital signature, a strict device authenticates the digital identity of the signatory.

A certifying agency recognized as a trusted third-party issue an electronic signature certificate to a signatory.

Equipped with this certificate, the signatory can thus carry out digital exchanges and sign remotely via electronic means by affixing a digital signature certified by an authority attesting to his identity.

It is therefore recommended to ensure that your trusted third party has obtained these certifications before using electronic software.

Criteria 4: Digital Signature for Public Procurement

Electronic signature standards for public procurement are in compliance with the requirements for strong authentication dematerialization.

The ChamberSign Certification Authority issues the necessary signature certificates to respond to public tenders on platforms dedicated to public procurement tenders.

These certificates work with a specific USB key, which is different from a conventional storage value USB key.

There are 3 different formats of digital signatures:

  • The PAdES format for signing documents in PDF format (Acrobat), as an attached signature, with only one file,
  • The CAdES format for signing documents in Word, Excel, and PDF formats, as a separate signature with 2 files,
  • The XAdes format for signing documents in XML format.

Criteria 5: The Benefits of Dematerialisation

Dematerialisation in general, and more particularly the electronic signature of documents, primarily accelerates administrative and commercial exchanges.

In the list of benefits, we can include:

  • Reduced processing time, since the signature is instantaneous,
  • Secure file flows,
  • Simplified and durable archiving,
  • Development of digital trust,
  • Considerable financial savings (end of paper, printing and related storage space),
  • Tracking of documents and the avoidance of human errors,
  • Increased productivity (time saving, end of excessive physical travel),
  • Standards promote international trade (security, transparency).

8 Tips for Creating a Digital Signature

To ensure that nothing is forgotten about the essential elements that constitute an online electronic signature, it is essential to observe the following safety points:

Tip 1: Use secure electronic signature software

No company wants a third party organization to access its information, or steal its identity!

Tip 2: Obtain an electronic certificate from a trusted third party that guarantees your digital identity

It is about having a certified digital identity to make oneself identifiable when requesting a signature or to confirm when signing.

Tip 3: Choose the right type of signature

Depending on the context, you must choose, for example, between the signature pad for receiving a client's signature, the pad to upload your own signature, or the trusted third party seal for documents that must have legal value.

Tip 4: Choose the right format

Focus on electronic signatures in PDF format for contracts.

Tip 5:  Send the right document format

Send a document format that cannot be modified, but that can be signed electronically.

Tip 6: Follow instructions

Distinguish between the signature and the signature request and follow the instructions step by step.

Tip 7: Plan ahead

Plan ahead for electronic archiving to enable effective management.

Tip 8: Prohibit free electronic signatures

Some online services allow you to sign a document electronically free of charge. appvizer strongly discourages this practice: your company may disclose sensitive or confidential data, without any confidentiality or security controls. As for the certification of your digital identity, there is still serious doubt. Instead, we recommend that you test tools free of charge for 30 days and attend a free demonstration beforehand: serious companies display their certifications and provide a consulting service to adapt to the needs of each company.
