Normalised Certificates

The purpose of a Normalised Certificate (NC) is to enable the creation of Advanced Electronic Signature (AES) in accordance with the Electronic Documents and Signatures Law of Macao SAR (EDS Law no. 5/2005) and others international standards.


The Law states that electronic records and their related Electronic Signatures are not to be denied legal effect, validity, or enforceability merely because they are in electronic form. Therefore it encourages the use of electronic signature as an alternative.

Benefits of using AES

AES was specially designed to provide you with the following necessary assurances, required for legal and secure electronic transactions:

  • Authentication (who you are);
  • Integrity (what you sent);
  • Non-repudiation (you can’t deny it);
  • Confidentiality (accessible only to those authorized to have access).


Some of the key advantages of using the Normalised Certificate are:

  • Verification of your personal electronic identity;
  • Protection and assurance of sensitive information and electronic transactions;
  • Detection of any fraudulent alteration of electronic documents and transactions;
  • The verification of authentication and validity of AES;
  • Creation of a non-reputable signature on electronic transactions or documents;
  • Eliminate any probability of accepting forged documents.


Optional Encipherment Certificate can also be used together, the main purposes of utilising the Encipherment Certificate are:

  • Protection of secret or confidential information from unintended audience;
  • State-of-the-art technology used for encryption.


Types of Normalised Certificate

Taking into consideration the different needs and rights of individual users and corporations, eSignTrust issues three similar but distinctively suitable Normalised Certificates.

  • Personal Normalised Certificate - is intended for a natural person with valid proof of identity. The usage of this Certificate is for signing documents on one’s own behalf.
  • Corporate Normalised Certificate - is designed for authorized personnel of a company, enterprise, institution or association etc, with a valid business registration certificate issued by Government of Macao SAR or a legal registered unit in Macao. The usage is intended for signing documents on behalf of his or her represented organisation.
  • Government Normalised Certificate – will be used by authorized personnel of a government agency or department. The usage is intended for signing documents on behalf of his or her government agency or department.


Application/Renewal Procedures

Identification Requirements

Since a Normalised Certificate will validate the identity of its holder, hence all AES applicants must be satisfactorily identified before they receive a Normalised Certificate. The applicants are required to meet in person with a Registration Authority (RA) Officer or representative during the identification process. If the applicants are outside Macao, the Registration Authority will provide online Identification and Authentication service to those who are eligible.


The Normalised Certificate and Encipherment Certificate together with their respective Private Keys can optionally be stored in a Smart Card; and in such case the holder of the certificates must supply a personal password during the registration to protect and access those keys.
