There are three types of digital signature certificates depending on the validation of identity and type of use. They are:
Class I DSC – Individuals get it for validating the email identification of the users and in situations where risk is minimal and here the signature is stored in software.
Class II DSC – Business organizations or individuals use this digital signature certificate to validate the information given by the subscriber in the application against the information available in a trusted consumer database and in other such situations where security risk is moderate. In this case a hardware cryptographic device is used for storing the signature.
Class III DSC – This digital certificate is directly issued by the certifying authority and it is required that the person applying for DSC must be present at the certifying authority’s premises and prove his/her identity in front of the authority and the security risk involved in this case is very high. In this case also a hardware cryptographic device is used for storing the signature.
