DSC Full Form - Digital Signature Certificate

Digital Signature Certificate(DSC)

  • DSC stands for Digital Signature Certificate. It's the digital equivalent of a physical or a paper document.
  • For example, driver's license, passport, and membership cards. This certificate acts as a symbol of identity of a private for a selected purpose, e.g., a driver's license identifies an individual who can legally drive the vehicle during a particular country specified in the license.
  • Furthermore, a digital signature is presented electronically to prove one's identity, to access information on the internet and to sign a document digitally.
  • A digital signature certificate contains information about the user's name, pin code, country, email address, date of issuance, the expiry date of the certificate, and name of the issuing authority.
  • It's a secure digital key which is issued by the certifying authorities to validate and certify the identity of an individual holding this certificate.
  • Digital signatures are created by using public-key encryption.

Benefits of a Digital Signature Certificate


  • It is often used to authenticate the private information and details of an individual while doing business online.

Reduced cost and time

  • You'll digitally sign a PDF file and send it to the receiver quickly, rather than signing a tough copy of a document and scanning it to send by email. Furthermore, the digital signature certificate holder isn't required to present physically to authorize a business.

Data integrity

  • The digitally signed documents can't be altered or edited; therefore the date remains safe and secure.
