A Digital Signature Certificate (DSC) is a digital key that can be used to verify and certify the identity of the person who holds it. Digital Signatures use the public vital encryptions for the creation of signatures.
Digital signature certificates (DSCs) contain information about the user, including their name, pin code and country. They also include email addresses, the date of issue of the certificate, as well as the name of the certifying authorities.
The Digital Signature Certificate type and purpose determine the type of DSC that one should apply for, depending on their needs. The certifying authorities can issue three types of Digital Signature Certificates.

Personal Identification Numbers (PIN), Codes and Passwords can also be verified using the same digital signature used to verify documents and mails.
Digital Signature Certificates are very much useful for cryptographic algorithms. It includes symmetric and asymmetric encryptions where the public key is used for encryption and the private key is used for decryption in asymmetric encryption. This means that messages can be encrypted by anyone using the public key but the same message can be decrypted only by the end receiver or sender using the private key. Apart from this, with the help of key encryption the DSC can be used to find the origin of the message.
With the onset of technology, issuing of fake certificates to get jobs or admissions in reputed colleges are increasing. Digital Signature Certificates comes as a Certification Authority that gives digital signature encryption to candidates in order to verify fake certificates.

DSCs are good news for Environmentalists - as it saves the use of paper by making digital signatures authorized and valid everywhere. They help with encryption of documents and saving them online in the servers. Physical documents transferring might sometimes need transport costs, which can be reduced in the case of DSCs, which also defers any security issues.
