Introduction:

A Digital Signature Certificate (DSC) is a safe and legally accepted electronic version of a regular signature. It works like a digital version of a handwritten signature and is used to confirm the identity of people or organizations in the digital space. DSC guarantees the genuineness and truthfulness of electronic files and dealings, offering a strong level of security and confidence in the online world.

Key Features of Digital Signature Certificate:

Identity Verification:

DSC is issued by Certification Authorities (CAs) after rigorous verification of the applicant’s identity. It acts as a reliable proof of identity in digital transactions, assuring the recipient of the authenticity of the signer.

Encryption and Decryption:

DSC enables secure encryption and decryption of electronic data. This ensures that the content remains confidential and can only be accessed by the intended recipient with the corresponding private key.

Data Integrity:

Any alteration or tampering of digitally signed documents can be detected immediately, as the digital signature becomes invalid after any alteration. It ensures data integrity and prevents unauthorized changes.

Non-repudiation:

DSC provides non-repudiation, meaning the signer cannot deny their involvement in a transaction or document once digitally signed. This feature adds a layer of accountability and reliability to electronic transactions.

Legal validity:

In many countries, including India, a digitally signed document has the same validity as a physically signed document. It is admissible as evidence in courts and government agencies.
