Certificate manager

Certificate manager is the main point through which you can execute active operations on managed certification authorities. The most important method is execute, which accepts CrtRequestDo. This method invokes (in a new transaction) the RequestEventType.EXECUTE event.

By default, the following processors are called after execute method was invoked:

1. RequestApproveProcessor - Ensures the start of the approval workflow process.
2. After approval, is called a processor for call the certification authority. Depending on the type of operation in the request, the appropriate processor is called.
   • To generate the certificate RequestGenerateProcessor.
   • To extend the validity of the certificate RequestRenewProcessor.
   • To revocate the certificate RequestRevocateProcessor.
3. If certificate atuhority works synchronously, the next "check state" processor is called (if works asynchronously, the event will be suppended). This processor ensures check of the request state. If request on the CA is already executed, then only sets state of the request to Executed. If request on the CA is not executed (asynchronouse case), calls the certificate authority again (for check current state). Depending on the type of operation in the request, the appropriate "check state" processor is called.
   • To generate the certificate RequestCheckStateGenerateProcessor.
   • To extend the validity of the certificate RequestCheckStateRenewProcessor.
   • To revocate the certificate RequestCheckStateRevocateProcessor.
4. On the end is calls "after action" processor. This processor ensures save results of the action (parse, save certificates, change of the state). Depending on the type of operation in the request, the appropriate "after action" processor is called.
   • To generate the certificate RequestAfterGenerateProcessor.
   • To extend the validity of the certificate RequestAfterRenewProcessor.
   • To revocate the certificate RequestAfterRevocateProcessor.

By default, the following processors are called after execute method was invoked:

1. RequestApproveProcessor - Ensures the start of the approval workflow process.
2. After approval, is called a processor for call the certification authority. Depending on the type of operation in the request, the appropriate processor is called.
   • To generate the certificate RequestGenerateProcessor.
   • To extend the validity of the certificate RequestRenewProcessor.
   • To revocate the certificate RequestRevocateProcessor.
3. If certificate authority works asynchronously, the event will be suppended.

Because the request was not executed yet (is in the state In progress), the we have to invoke the refresh method on the CertificateManager.

By default, the following processors are called after refresh method was invoked:

1. If request on the CA is not executed (asynchronouse case), calls the certificate authority again (for check current state). If request is still not executed, the event will be suspended again. Depending on the type of operation in the request, the appropriate "check state" processor is called.
   • To generate the certificate RequestCheckStateGenerateProcessor.
   • To extend the validity of the certificate RequestCheckStateRenewProcessor.
   • To revocate the certificate RequestCheckStateRevocateProcessor.
2. On the end is calls "after action" processor. This processor ensures save results of the action (parse, save certificates, change of the state). Depending on the type of operation in the request, the appropriate "after action" processor is called.
   • To generate the certificate RequestAfterGenerateProcessor.
   • To extend the validity of the certificate RequestAfterRenewProcessor.
   • To revocate the certificate RequestAfterRevocateProcessor.
