Why every certificate ships with a High Trust Token
At BestDSC we never sell a Digital Signature Certificate on its own. A certificate stored as a plain file can be silently copied, emailed or backed up without your knowledge — and once copied, it can be used to sign documents in your name. Every certificate we issue is installed on a High Trust Token, a tamper-resistant hardware cryptographic device (FIPS-certified), so your signing key physically never leaves the token.
This design prevents the most common form of DSC misuse. Because the private key is generated and locked inside the token, it cannot be exported or duplicated. Signing is only possible when the physical token is plugged in and unlocked with your PIN — giving you a clear, defensible audit trail for every signature.
The legal protection matters. Under the Information Technology Act, a digital signature carries the same legal standing as a handwritten one. Keeping the key on secure hardware means you can confidently attest that any signature made with your certificate was authorised by you — critical if a filing, tender bid or contract is ever disputed.
You get the token included, configured and delivered to your address. No separate purchase, no loose certificate files, and no compromise on security.
