Digital Signature Certificate (DSC)

A Digital Signature Certificate (DSC) is an electronic certificate that acts as a digital equivalent of a physical signature for online transactions and document signing. It verifies the identity of the signer and ensures the authenticity and integrity of the signed document. DSCs are issued by Certifying Authorities (CAs) and are based on public-key cryptography.

Key Aspects of a Digital Signature Certificate:

• ✓
  Authentication: DSCs verify the identity of the signer, ensuring that the document is actually from the claimed sender.
• ✓
  Integrity: Digital signatures ensure that the document hasn't been tampered with after signing.
• ✓
  Non-repudiation: DSCs prevent the signer from denying they signed the document, as the digital signature is unique and tied to their identity.
• ✓
  Security: DSCs utilize encryption technology to protect the information and ensure secure transactions.
• ✓
  Legal Recognition: DSCs are legally recognized in many jurisdictions for various online transactions, including government filings and business dealings.

Components:

A DSC typically includes the signer's name, email address, the issuing CA's name, and the certificate's validity period.
