Enterprise Digital Signing with DSC Certificate
Sign documents using your DSC digital certificate. PKI compliant, legally valid and enterprise ready.
What is a DSC Digital Signature?
A Digital Signature Certificate (DSC) is a PKI-based cryptographic credential issued by a licensed Certifying Authority under the Controller of Certifying Authorities (CCA), India. It binds your identity to a private-public key pair, so you can sign PDFs, MCA/ROC filings, GST returns and tenders with tamper-evident, cryptographically verifiable proof built into every document.
PKI-Based Cryptography
Every signature uses an asymmetric public/private key pair issued by a licensed CA, making forgery mathematically infeasible.
Token & HSM Ready
Works with USB eTokens, smart cards and HSM-based Class 3 certificates — plug in and sign directly from the hardware.
Long-Term Validity
Timestamped signatures stay independently verifiable for years, even after the certificate itself expires.
CCA-Licensed Authorities
Supports certificates from every major CCA-licensed CA — eMudhra, Sify, NSDL, Capricorn and more.
