A Digital Signature is a cryptographic electronic signature used to verify the identity of the signer and confirm that a digital document has not been altered after it was signed. It is created using a private key and verified using the corresponding public key through Public Key Infrastructure (PKI). In India, Digital Signatures are legally recognized under the Information Technology Act, 2000 and are widely used for government filings, contracts, compliance, and secure business transactions.

A Digital Signature Certificate (DSC) is a secure digital credential that verifies the identity of an individual or organization when signing electronic documents or accessing online services. It uses Public Key Infrastructure (PKI) and cryptographic technology to create legally recognized digital signatures, protect document integrity, and authenticate the signer. In India, Digital Signature Certificates are issued by licensed Certifying Authorities (CAs) operating under the regulatory framework of the Controller of Certifying Authorities (CCA).

One can easily buy a digital signature certificate online via registered service providers and by individuals and organizations themselves.

Yes. The use of e-tendering systems requires the use of a digital signature certificate.

Digital signature involves encryptions and certificates. A signature on the electronic message may be typed text or photograph.

Digital signature involves the usage of cryptographic keys to sign documents securely using the public and the private keys.

A PDF can be digitally eSigned by uploading it to a trusted eSign platform, verifying your identity, placing the signature where required, and completing the signing process using a Digital Signature Certificate (DSC) or Aadhaar-based eSign. The signed PDF becomes tamper-evident and can be verified by anyone using standard PDF readers.

A valid Digital Signature Certificate together with the signing software can be used to sign Form 16A digitally.

A Digital Signature Certificate or approved eSign services can be used to make a digital signature.

A Digital Signature Certificate (DSC) works by using Public Key Infrastructure (PKI) and cryptographic technology. When a document is digitally signed, a unique hash of the document is created and encrypted using the signer's private key. Anyone receiving the document can verify the signature using the corresponding public key stored in the Digital Signature Certificate, ensuring the document is authentic, unchanged, and signed by the rightful owner.

Online approvals and documentation submission are performed by means of digital signatures in AICTE.

CERSAI operates the registration and verification of records of security interests online through the use of digital signatures.

One of the ways to enter a digital signature business is to be a partner to an authorized service provider.
