On December 19, 2017, the Ministry of Information and Communications issued Circular 41/2017/TT-BTTTT specifying detailed regulations on the verification of digital signatures on electronic documents.

Circular 41 stipulates that the verification of digital signatures on electronic documents is carried out as follows:

Additionally, Circular 41 specifies that the digital signature on an electronic document is valid when the verification and authentication of the digital certificate information of the signer at the time of signing are still valid, the digital signature is created correctly by the private key corresponding to the public key in the digital certificate, and the electronic document ensures its integrity.

Note that information about the digital signer; the agency or organization signing the electronic document must be managed in a database accompanying the digital signature verification software.
