What Is a Cloud-Based Signature Certificate?
A cloud-based signature certificate is a digital certificate used to create and verify qualified electronic signatures (QES). Unlike certificates stored on local devices, this certificate is stored and managed in the cloud.
What Does the Certificate Contain?
- Signer's name and email address
- Public key linked to the signer’s private key
- Issued by a Certification Authority (CA) that verifies the signer’s identity and the certificate’s validity
Benefits of a Cloud-Based Signature Certificate
1. Convenience
Access your signature from any internet-connected device—no need to carry a physical token.
2. Security
Cloud providers typically enforce robust security protocols to protect your certificate’s confidentiality and integrity.
3. Cost-Effectiveness
No need to invest in hardware or manage on-premise infrastructure.
4. Scalability
Easily scale usage up or down without adding physical resources.
Risks and Considerations
1. Provider Dependence
If your provider shuts down or is breached, you could lose access to your certificate.
2. Internet Dependency
Access requires a stable internet connection.
3. Legal Jurisdiction
Your certificate might be governed by laws in the country where the provider’s servers are located.
