Certificate renewal is described. A processing device searches a certificate authority (CA) database of digital certificates to identify a certificate that satisfies an expiration condition for automatic renewal. The processing device renews the certificate as a renewed certificate without any user interaction. The processing device is to renew the certificate in view of the expiration condition. The expiration condition includes an expiration of the certificate. When renewing of the certificate, the processing device reuses a key of the certificate for the renewed certificate and sets a new expiration date for the renewed certificate.
