Introduction to Digital Signature
A digital signature is an electronic signature form used for authentication of the 
identity of the communicator or an authority signing the document. It ensures 
authenticity and originality of the content of the communication or the 
document. Digital Signatures remain unchanged throughout the communication 
or documentation, they are easily transportable and it cannot be imitated by 
anyone else. It also makes sure that the sender cannot deny the content sent 
via that signed document.

Understanding Digital Signature Certificate
Digital signature certificate can be better understood as the electronic 
alternative to physical or paper certificates such as driving license, PAN 
Card, passport, etc. Digital Certificates are proof of the identity of a person 
having a specified purpose. For example, a passport identifies a citizen’s 
identity with relation to a nationality and that citizen is eligible to legally 
travel to any country on a grant of permission. Under these identity 
requirements, the digital certificate is used to electronically prove a citizen’s 
identity and helps access to information or services via the internet or other 
electronic mediums or to sign documents digitally.

Digital Signature Web Application Process
A digital signature certificate links the identity of a person with a pair of 
electronic keys, i.e. public and private keys, endorsed by a CA. The 
certificate consists of information related to the user’s identity (Like: 
name, pin code, country, email address, certificate issue date, and the 
Certifying Authority Name).

The keys are complementary to each other and one cannot work without 
the presence of another. The browsers and servers to encrypt and decrypt 
the information of the certificate user during the complete process. The 
private key can be stored on the user’s hard disk, computer or any external 
device. The user controls the access and it only works with the assigned 
password. In case of mismatch of the two, the authentication process fails. 
This ensures that only authorized personnel can use the Digital signatures 
whereas the unauthorized ones cannot access the data.
