Class 3 Digital Signature Certificate
Class 3 is the digital signature certificate used across most government and compliance portals in India. DSCBUY.IN helps you confirm the exact type you need, then sends you to the official Capricorn application.
Who needs it
Signing, encryption, or both
Signing
Proves the document or filing came from you and hasn't been altered. Used for most portal filings.
Encryption
Protects confidential information, such as tender documents, so only the intended recipient can read it.
Signing + Encryption
A combined certificate for portals that require both, such as some tendering and customs systems.
What you'll need
A USB crypto token
Your DSC is stored on a token, not a file. If you don't have one, we supply the models used with Capricorn certificates.

How long does it take to get a DSC?
Processing time is set by Capricorn's KYC and verification process and can vary. The official application shows current timelines.
Do I need a new DSC for every portal?
Usually no — one valid Class 3 DSC of the right type can typically be used across the portals it supports. Confirm with the specific portal if in doubt.
Can DSCBUY.IN issue my certificate directly?
No. Capricorn Identity Services Pvt. Ltd. is the Certifying Authority. DSCBUY.IN guides you and sends you to their official application.
