What is a Public Key Certificate? When to Use a Public Key Certificate (PKC)?

In the upcoming new national procurement network system, a public key certificate (PKC) will be introduced for entities to interact with the system.

A PKC, or public key certificate, is a digital signature provided by organizations offering public key signature services for subscription use. To be more precise, it is an electronic signature currently employed by businesses to digitally sign contracts and necessary documents within the online environment.

PKCs have the same legal validity as personal signatures or corporate seals. The primary purpose of using PKCs is to authenticate the information of organizations/individuals when selecting contractors and investors.

Specific use cases for PKCs include:

  • Bid solicitor use PKCs to publish Tender Notice, prequalification notices, bid openings, and responses to clarifications regarding tender documents, bid dossiers, cancellations, etc.
  • Contractors/Investors use PKCs to sign prequalification documents, bid dossiers, and to confirm information on capability profiles, respond to clarifications on bid documents, and extensions of bid validity.
  • Investors use PKCs to confirm bid cancellations, resolve issues, and provide recommendations on the national procurement network system.
  • Authorized agencies use PKCs to cancel bids, resolve issues, and provide recommendations on the national procurement network system.

How to Register for a Public Key Certificate (PKC)?

PKCs will be issued by public key certificate service providers in Vietnam. To use PKCs, organizations and units should directly contact the PKC service providers to register. Currently, the national procurement network system accepts PKCs from 18 service providers, as shown below:

Due to the nature of PKCs being electronic signatures, similar to digital signatures, which organizations use for signing in the online environment, if a company already has an electronic signature for their accounting department, it can be used for online bidding by the company. However, sharing PKCs or digital signatures with other departments should only be done for small- to medium-sized companies and for occasional transactions.

For larger organizations or those performing frequent, specialized tasks, it's recommended to register separate PKCs or digital signatures. A company can have multiple digital signatures, and for an effective procurement process, a separate digital signature/PKC can be registered for the procurement department. This ensures secure information sharing between departments and simplifies management.

Note when Using Public Key Certificates (PKCs):

  • New or registered PKCs remain valid at the time of use on the new national procurement network system.

  • Each PKC is registered for use with a single organization/unit on the system. If an organization/unit has multiple roles (bid invitation unit, contractor, investor, etc.), the PKC can be registered once and used for multiple roles.

  • Public PKC can be shared by participating accounts/business accounts belonging to the same organization/unit

  • Only use PKC of organizations and businesses on the System.

  • For first time PKC registrants need to install Drive for PKC while USB Token is plugged into the computer

  • The unit needs to install and start the Agent application when postingsign digital certificates on the new national network. 

  • A participating account can only register 1 PKC. In case the unit has previously registered for PKC and wants to update the PKC, please select the new PKC recorded from the USB Token connected to the computer.

  • Participating accounts and business accounts created by the same account can register to use the same PKC using the function assign a digital certificate at the Create/Edit business account screen.

  • Change PKC: If the Bid solicitor/Investor has packages that have not yet been opened for bidding but needs to change the PKC, these unopened packages cannot be opened using the new PKC. Therefore, the Bid solicitor/Investor must ensure that all the bidding packages are successfully opened before changing the PKC.
