IT Act 2000

Ensures signatures comply with the statutory requirements of the Indian Information Technology Act.

Indian Digital Signature Standards

Aligned with specific Controller of Certifying Authorities (CCA) guidelines for digital signature validity.

Global PKI Security Standards

Meets international cryptographic and PKI guidelines for cross-border trust and enterprise compliance.

This makes it suitable for industries where document security and regulatory compliance are critical.

Support for Crypto Tokens and PFX Certificates

Our Digital Signature Solution supports multiple certificate and cryptographic storage options, including Crypto USB Tokens, PFX Certificates, and Document Signer Certificates. The platform is compatible with FIPS 140 Level 2 and Level 3 security-compliant cryptographic devices. Private keys remain securely protected within hardware devices, minimizing unauthorized access risks and enhancing enterprise-grade security.

Bulk PDF Signing Automation

Organizations handling large volumes of documents can automate signing operations with advanced bulk signing capabilities.

Bulk Signing Features

Batch PDF signing

Process thousands of PDF files at once in the background with minimal server load.

Ideal for Signing

Invoices & Financials

The solution significantly reduces manual workload while maintaining secure signing standards.

Visible and Invisible Digital Signatures

Visible Signatures

Customize the visual appearance of signatures using branding elements like company logos, signer information, time stamps, signature placements, and custom coordinates.

Invisible Signatures

Invisible signatures support backend validation and silent verification workflows without affecting document appearanceβ€”perfect for background security compliance.

This flexibility allows organizations to meet both branding and security requirements.

Advanced Security Features

Our PKI Signing Solution includes multiple enterprise security enhancements such as:

Green Tick Validation

Enables standard digital signature validation indicators for authenticity, trusted by PDF readers.

RFC 3161 Timestamp Authority Support

The platform supports RFC 3161-compliant Timestamp Authority (TSA) integration for long-term digital signature validation.

Trusted Time Verification

Ensures signatures contain a tamper-proof timestamp from an official, independent TSA provider.

Timestamping enhances the legal and evidentiary value of digitally signed documents.

PAdES and CAdES Compliance

PKI Signing Solution supports internationally recognized digital signature standards, including:

PAdES (PDF Advanced Electronic Signatures)

Adheres to PDF-specific signing profiles, ensuring that signature visual representation and metadata comply with global standards.

CAdES (CMS Advanced Electronic Signatures)

Adheres to Cryptographic Message Syntax rules for signing raw data payloads and binary logs securely.

These standards ensure interoperability, compliance, and secure document exchange across enterprise ecosystems.
