A Digital Signature Certificate is only legally valid if it is issued by a Certifying Authority (CA) licensed by the Controller of Certifying Authorities (CCA) under the IT Act, 2000. Here is a plain-English guide to what a CA is, the main licensed CAs in India, and where a DSC provider like DSC Buddy fits in.
A Certifying Authority (CA) is an organisation licensed by the CCA (a body under the Ministry of Electronics & IT) to issue Digital Signature Certificates. The CA verifies your identity, binds it to a cryptographic key pair, and issues the certificate — which is what makes your digital signature legally enforceable in India. Only CCA-licensed CAs may issue DSCs; the authoritative, current list is maintained by the CCA at cca.gov.in.
The best-known CCA-licensed Certifying Authorities that issue Class 3, DGFT and Document Signer certificates include:
| Certifying Authority | Known for |
|---|---|
| eMudhra | One of India's largest CAs; publicly listed |
| (n)Code Solutions | A GNFC (Govt of Gujarat) undertaking |
| Capricorn | Widely used CA with a large partner network |
| IDSign | Certifying Authority (Verasys Technologies) — DSC Buddy's CA partner |
| XtraTrust | CCA-licensed CA for Class 3 & DGFT certificates |
| PantaSign | Pantagon Sign Securities — Class 3 & DGFT DSCs |
| VSign | CCA-licensed Certifying Authority |
| ProDigiSign | Certifying Authority for digital signatures |
| SafeScrypt (Sify) | One of India's earliest Certifying Authorities |
| NIC / CDAC / IDRBT | Government CAs (govt use & the banking sector) |
Names are listed for reference. The official, always-current list of licensed CAs is published by the Controller of Certifying Authorities (CCA). A DSC issued by any licensed CA carries the same legal validity.
A Certifying Authority issues the certificate. A DSC provider (like DSC Buddy) is a channel partner that handles your onboarding — collecting documents, running paperless Aadhaar eKYC, supplying the USB token, and getting the certificate issued through a licensed CA. You get faster service and support, and the certificate is issued by the licensed CA, so it is fully legally valid.
