Troubleshooting Common Issues With A PKI System

Public Key Infrastructure (PKI) systems are essential to digital certificate management, and the Keyfactor platform provides organizations with a comprehensive PKI solution. In this blog post, we will discuss some of the most common PKI system issues and how to troubleshoot them. We’ll also provide tips for avoiding these problems in the future so you can keep your organization’s PKI system running smoothly.

1. Revoked Certificates

One of the primary problems with PKI is revoked certificates. A revoked certification has been invalidated and is no longer considered to be trusted. A certificate may be revoked for several reasons, such as expiration, key compromise, or an employee leaving an organization. Users cannot access secure services or exchange information without a valid certificate. To fix this issue, organizations can implement a certificate revocation list (CRL) or an online certificate status protocol (OCSP) to ensure that revoked certificates are not in use.

2. Certificate Expiration

Certificates have a lifespan that varies from one organization to another. A certificate’s expiration means it is no longer valid, which can cause problems for users who rely on secure communication. Certificate expiration can be caused by human error, such as forgetting to renew the certificate or not having a clear policy. To avoid this issue, having a clear certificate lifecycle management policy and monitoring certificates for expiration and renewal is essential.

3. Misconfigured Certificate

A misconfigured certificate has been misconfigured or has the wrong key length. A misconfigured certificate can cause communication errors and authentication problems for users. To resolve this issue, organizations should ensure that certificates are correctly configured, have the right key length, and are validated before production.

4. Certificate Chain Errors

Certificate chain errors occur when the root certificate is not correctly installed or has expired. This can lead to trust issues and cause secure communication to break down. The root certificate is the parent of all certificates, and it is essential to ensure that it is up-to-date and installed correctly. To fix the certificate chain issue, organizations should ensure that the root certificate is in place and has not expired.

5. Caused By Malware Or Hackers

Malware or hacker attacks may cause PKI to break down. When attackers gain access to a system, they can launch a man-in-the-middle attack that intercepts and alters communication data. Hackers can also exploit vulnerabilities in PKI systems, leading to trust issues and insecure information exchange. Organizations should invest in malware detection and prevention systems and implement best practices for secure communication.

6. Expired Crls

An expired certificate revocation list (CRL) can cause problems with authentication and secure communication. A CRL is a list of revoked certificates that must be kept up-to-date. If the CRL has expired, users may be allowed to use revoked certificates or those not issued by the organization, leading to security issues. To resolve this issue, organizations should regularly update their CRLs and monitor them for expiration.

7. Poor Key Management

Poor key management can lead to security vulnerabilities and weak encryption. Keys must be stored securely and managed properly to ensure the safety of data and communications. Organizations should have a secure key management system that includes multiple layers of protection, such as strong passwords, two-factor authentication, and regular backup procedures.


In conclusion, PKI systems are critical for secure communication over the Internet. However, as with any complex system, issues may arise that need troubleshooting. Organizations can ensure that their PKI systems run smoothly and securely by understanding the common issues and their possible solutions. As cyber threats evolve, investing in detection and prevention systems is essential to keep your PKI system secure. With this knowledge, your organization can enjoy secure communication and peace of mind.
