Abstract:
1. A method for replacing a current security certificate, comprising: producing a security certificate request at a first device, the security certificate request including a request for a replacement security certificate to replace a current security certificate, the replacement security certificate enabling encrypted communication between the first device and a second device; sending the security certificate request to a security certificate vendor; receiving the replacement security certificate from the security certificate vendor; installing the replacement security certificate within a verification layer of the first device; converting the replacement security certificate to a compliant proprietary format associated with the second device; transmitting the replacement security certificate that has been converted to the compliant proprietary format to the second device; verifying that the second device has installed the replacement security certificate, the verification further verifying that the replacement security certificate enables encrypted communication between the first device and the second device; in response to completion of the verification, archiving the current security certificate as a previously used certificate within an archive database, wherein the archive database stores one or more previously used certificates; activating the replacement security certificate for use in encrypting communications between the first device and the second device; in response to determining the replacement security certificate has failed, reactivating the previously used certificate and replacing the replacement security certificate with the reactivated previously used certificate; verifying encrypted messaging capabilities between the first device and the second device using the replacement security certificate; and in response to being unable to verify encrypted messaging capabilities between the first device and the second device using the replacement security certificate, reactivating the archived previously used certificate for use in encrypting communications between the first device and the second device.
