Certificate manager
A computing resource service provider provides a certificate management service that allows customers of the computing resource service provider to create, distribute, manage, and revoke digital certificates issued by public and/or private certificate authorities. In an embodiment, customers may use the certificate management service to generate private certificate authority which can issue signed certificates to network entities within the customer enterprise. In an embodiment, the private certificate authority is hosted by the computing resource service provider, and the certificate management service automates the renewal and management of active certificates. In an embodiment, the certificate management service allows customer applications to create, renew, and revoke certificates issued by both private and public certificate authorities via an application programming interface.

accessible, through the application programming interface, by the plurality of certificate authorities; and
causing, based at least in part on the identification, the operation to be performed by the second private certificate authority by at least providing, over a second communication channel comprising a distinct protocol from the first communication channel, the second private certificate authority with the second request through an endpoint of the certificate management service within an environment.
6. The computer-implemented method of claim 5 , wherein:
the operation is a certificate signing operation; and
performing the operation is accomplished by at least generating a digital signature of the digital certificate.

the computer system is a virtual computer system instance; and
the computer system is provisioned by at least provisioning the virtual computer system instance.
8. The computer-implemented method of claim 5 , wherein the second private certificate authority is identified by at least:
identifying subject information of the digital certificate; and
determining that the second private certificate authority is associated with the subject information.
9. The computer-implemented method of claim 5 , wherein the parameter includes information that allows use of a private cryptographic key to be associated with the first private certificate authority.
10. The computer-implemented method of claim 9 , wherein the information is an encrypted version of the private cryptographic key that, as a result of being downloaded to a hardware security module, allows the private cryptographic key to be used to generate a digital signature.
11. The computer-implemented method of claim 5 , wherein the operation is a certificate signing operation, a certificate renewal operation, or a certificate revocation operation.
12. The computer-implemented method of claim 5 , further comprising:

performing the operation using the hardware security module.
13. A non-transitory computer-readable storage medium storing thereon executable instructions that, as a result of being executed by one or more processors of a computer system, cause the computer system to at least:
provide, to a client computer system, an interface for creating a private certificate authority and performing an operation to one or more digital certificates;
obtain a request in response to the interface to create a first private certificate authority over a first communication channel within a first network provided by a computing resource service provider;
provision, at least in part by a certificate management service, a computer system to operate as the first private certificate authority in accordance with a parameter specified with the request within the first network;
