Class 3 Certificates provide the highest level of assurance as these certificates are issued only after the Dohatec CA/RA verifies the Subscriber Identity in various ways. Apart from the verification procedures of class 1 and class 2 certificates, class 3 certificates verification process may involve the physical presence of the Subscriber, if required, at the Dohatec CA’s office. These validation procedures provide stronger assurances of a Subscriber’s identity than Class 2 Certificates.

The RA verifies the details of the Subscriber and only after ascertaining that the details are correct will recommend the Dohatec CA to process the certificate request.

The Private keys of the Class 3 Certificates should be generated and stored in tamper proof cryptographic devices such as FIPS 140-2 Level 2 supported smart cards or tokens.

Class 3 Certificates have the highest level of assurance and hence can be used where ever there is a need for legally valid digital certificates such as e-commerce transactions, e-filing etc.

Class-3 Certificates issued by the Dohatec CA are legally valid under the Bangladesh Information, Communication and Technology Act, 2006.
