Is there a web app or gui to do a centralized certificate authority (ssl)?

Question

Digital certificates

Roughly speaking, generate new certificates with one left and keep everything in order

Answer 1

The CA usually performs the following tasks: - Issuing a
certificate based on a prepared CSR -
Revoking a certificate -
Generating a CRL
- Managing certificate templates
- Keeping statistics, managing lists of issued certificates CA management can be a Certification Center snap-in if you have CA deployed on Windows. She solves all the usual tasks of the SA. The task of generating a CSR and generating a ready-made PKCS # 12, which is needed for mail to work - in order to use certificates in corporate correspondence - I solve with several bicycles, they are very primitive, but they work :)
Well-known CAs do not allow you to generate a CSR through a form, but only accept a ready-made one. And they do not send PKCS # 12 - but only a certificate, well, also their root ones.
