This article will explain why you should not to reuse CSRs. At Hosted.com®, we advise against reusing private keys or Certificate Signing Requests (CSRs) across multiple SSL certificates. Each SSL certificate should have a unique key pair to ensure the integrity of encryption and maintain the highest level of security.
Reusing keys creates vulnerabilities because if a private key is compromised, every certificate using that key is also at risk. Unique CSRs and private keys prevent attackers from exploiting multiple certificates simultaneously, reducing exposure to potential breaches.
By generating unique private keys and CSRs for every SSL certificate, Hosted.com® clients maintain powerful security and prevent vulnerabilities that could compromise multiple certificates at once.

- Compliance Standards: Certificate Authorities require unique key pairs for new certificates to comply with security standards.
- Renewals: Generate a new CSR and private key during each certificate renewal to maintain encryption integrity.
- Hosted.com® Tools: Hosted.com® provides tools in cPanel and the client portal to easily generate unique CSRs.
- Best Practices: Store private keys securely in encrypted formats or on secure servers.
- Impact of Reuse: Reused keys can invalidate security trust indicators, causing browsers to display warnings.
