What is a Document Signing Certificate?
A document signing certificate is a digital credential issued by a trusted Certificate Authority (CA) that ensures the authenticity, integrity, and security of electronic documents. It binds your identity to your digital signature, confirming that the document originates from a verified source and has not been altered.
These certificates use robust encryption to create tamper-proof digital signatures that are legally recognized and compliant with global standards. By applying a document signing certificate, you add a layer of trust, making it clear to recipients that the document is legitimate and secure.
Whether you’re a business professional, legal expert, or organization handling sensitive data, document signing certificates are an essential tool for protecting your digital transactions and building credibility.
Benefits of Document Signing Certificates
Bulletproof Encryption and Unrivaled Security
A document signing certificate uses 2048-bit encryption, making it virtually unbreakable with current technology. This ensures your documents are tamper-proof and secure from unauthorized alterations.
Extra Protection for Your Keys
Your private key is securely stored in an iKey USB token with two-factor authentication, providing an extra layer of security to your digital signature process.
Unquestionable Credibility
Digitally signed documents verify the sender’s identity, meeting legal requirements like the U.S. Federal ESIGN Act and international laws, ensuring compliance and trustworthiness.

Organization Validation and Improved Trust

Full Browser Compatibility
Document signing certificates work seamlessly with leading browsers, Microsoft Office, and open-source platforms like LibreOffice, allowing secure document signing on mobile and desktop devices.
How Do Document Signing Certificates Work?
Document signing certificates use public key infrastructure (PKI) to secure and validate digital signatures. Here’s a step-by-step breakdown of how they work:
- Identity Verification: The Certificate Authority (CA) verifies the identity of the certificate requester through a rigorous validation process. This step ensures only legitimate individuals or organizations receive the certificate.
- Digital Signature Creation: Once issued, the certificate pairs with a private key stored on a secure token (e.g., iKey USB). When signing a document, the private key encrypts the data, creating a unique digital signature.
- Signature Validation: The recipient of the document uses the signer’s public key, embedded in the certificate, to decrypt and verify the signature. This process ensures the document’s authenticity and confirms it hasn’t been tampered with.
- Tamper-Proof Security: Any alteration to the document invalidates the digital signature, alerting recipients to potential breaches.
- Legal Compliance: These certificates comply with global digital signature laws like the U.S. Federal ESIGN Act and eIDAS in Europe, making them legally binding.
By combining advanced encryption, identity validation, and tamper detection, document signing certificates offer a reliable and secure solution for protecting digital transactions.

Great selection of certificates with a clear definition of properties for each certificate makes it easy to choose the right one.
Easier and cheaper than going directly and ordering via the vendor, thank you for the information and the simple shopping experience.
Excellent customer service when I ordered the wrong cert! The support team then helped me get the correct cert and refunded me on the incorrect cert I bought! Very fast and a happy customer.
One of the most reliable SSL brands. If you need to secure subdomains and can afford it, don’t think twice. Get it.
The price seems fair for an EV certificate, especially the two-year deal. Unlike my previous provider, which I won’t advertise here, at SSL Dragon, the buying steps are easier and better explained.
Always a pleasure doing business with SSL Dragon. Thawte certificates consistently deliver the highest encryption and customer trust.
Was assigned to secure several NGO sites. Picked this certificate because of a higher warranty and reasonable price. It’s always a pleasure to work with SSL Dragon.
Simply the best. Easy to buy and configure. Plenty of features. Can display the site seal in different languages as well.
A top-class product from a reputable company. Credits to SSL Dragon as well, for a smooth buying experience and excellent price.
This is the third SSL Certificate I buy from SSL Dragon, and the first one from GeoTrust. All I can say is the certs work as described in the specs, and the support is very friendly.
The SSL wizard recommended this certificate for our e-stores. We’re already on the third renewal, and during all these years, didn’t have a single issue with it.
