Digital Signature

Key Components of Digital Signature:

1. Digital Signature Certificates (DSC):
   • Types of Certificates:
     • Class 1: Validates the identity of individuals and ensures the email address provided is valid.
     • Class 2: Verifies the individual’s identity against a trusted database, commonly used for company-related activities.
     • Class 3: Offers the highest level of security and is used for secure online transactions, including e-tendering and e-auctions.
2. Authentication and Security:
   • Encryption: Digital signatures use cryptographic techniques to encrypt the signature and ensure that the document has not been altered since it was signed.
   • Public and Private Keys: Digital signatures rely on a pair of cryptographic keys – a public key and a private key – where the private key signs the document, and the public key verifies it.
3. Legal Validity:
   • Legal Framework: In India, the use of digital signatures is governed by the Information Technology Act, 2000. Digital signatures are legally recognized and have the same legal standing as traditional handwritten signatures.
