Digital Certificates are the digital equivalents (i.e. a driving license identifies someone who can legally drive in a particular country.

Digital Certificates serve as an identity of an individual for a certain purpose, e.g. Also an Individual is required to obtain Class-2 DSC with PAN Encryption for e-filing his return with Income Tax, India. electronic format) of physical or paper Certificates like your driving license, passport or membership cards.

By Using This Certificate You can Participate/Bid in Any Kind of On-line Tenders/Auction across India. To participate in the e-tendering process, every vendor is required to use a Class 3 Digital Signatures Certificate.

As e-filing is made compulsory in ROC, every director / signing authority needs to have their Digital Signature Certificate. It typically contains your identity (name, email, country, APNIC account name and your public key).

A digital certificate is an electronic “credit card” that establishes your credentials when doing business or other transactions on the Web.

Class 3 Digital Signature Certificate is the upgraded version of Class 2 Digital Signature Certificate. Digital Certificates use Public Key Infrastructure meaning data that has been digitally signed or encrypted by a private key can only be decrypted by its corresponding public key. A Digital Signature Certificate (DSC) is a secure digital key that certifies the identity of the holder, issued by a Certifying Authority (CA).

Its now mandatory to obtain Class-2 or Class-2 with PAN Encryption Digital Signature Certificate for any person who is required to sign manual documents and returns filed with ROC as per MCA21. Likewise, a Digital Certificate can be presented electronically to prove your identity or your right to access information or services on the Internet.

Difference between Encryption and Signing

Message encryption provides confidentiality. Allows users to encrypt document with the public key which can be decrypted only with the corresponding private key. To put it in simple terms when encrypting, you use their public key to write message and recipient uses their private key to read it. One of the most secure way protecting confidential documents.

Message signing binds the identity of the message source to this message. It ensures data integrity, message authentication, and non-repudiation altogether. When signing, you use your private key to write message’s signature, and they use your public key to check if it’s really yours.


To create a digital signature, signing software — such as an email program — creates a one-way hash of the electronic data to be signed. The private key is then used to encrypt the hash. The encrypted hash — along with other information, such as the hashing algorithm — is the digital signature.

The reason for encrypting the hash instead of the entire message or document is that a hash function can convert an arbitrary input into a fixed length value, which is usually much shorter. This saves time as hashing is much faster than signing.

The value of a hash is unique to the hashed data. Any change in the data, even a change in a single character, will result in a different value. This attribute enables others to validate the integrity of the data by using the signer’s public key to decrypt the hash.


While digital signature is a technical term, defining the result of a cryptographic process that can be used to authenticate a sequence of data, the term electronic signature — or e-signature — is a legal term that is defined legislatively.
