Electronic signing or digital signing is used in different ways to establish authenticity and non-repudiation. It is performed using long-term and short-term signature certificates with the help of hardware security modules. What Is a Long-Term Signature Certificate? Long-term signature certificates are obtained from the Controller of Certifying Authorities in India (CCA) - licensed CAs. The user/subscriber needs to provide all the required information (e.g., identity, geographic location, etc.) according to the class of certificate they need. Usually, class-2 and class-3 certificates are obtained for legally valid signatures. And, users have complete control of their private keys and certificates. What Is a Short-Term Signature Certificate? Short-term signature certificates are used for instant document signing. These certificates expire in a very short period of time. Practically, each document signing requires a new certificate.
