3. A method according to claim 1, wherein said instructions are further executable to achieve the functions of:

generating a new asymmetric key pair; and

installing a generated private key of a new asymmetric key pair to an identified destination managed server; and

wherein a generated certificate signing request includes a generated public key of a new asymmetric key pair.

4. A method according to claim 1, wherein said instructions are further executable to install a received certificate signed by a certificate authority by a network interface provided by a web interface of a web server installed to an identified destination managed server.

5. A method according to claim 1, wherein said instructions are further executable to install a received certificate signed by a certificate authority by a shell interface to an identified destination managed server.

6. A method according to claim 1, wherein said instructions are further executable to install a received certificate signed by a certificate authority by an agent program installed to an identified destination managed server.

7. A method according to claim 1, wherein said instructions are further executable to restart a destination server program.

8. A method according to claim 1, wherein said instructions are further executable to restart a destination server computer.

9. A method according to claim 1, wherein said instructions are further executable to notify an administrator to restart a destination server program or destination server computer.

10. A method according to claim 1, wherein said instructions are further executable to confirm the installation of a received certificate to a destination server following the performance of a set of installation steps.

11. A method according to claim 10, wherein said instructions are further executable to generate an alert to an administrator if the installation of a received certificate to a destination server is not confirmed.

12. A method according to claim 1, wherein said instructions are further executable to achieve the functions of:

informing an administrator of a certificate for which expiration has been detected;

prior to said transmitting, requesting approval to renew a certificate for which expiration has been detected; and

receiving, in response to a request for approval, an indication from an administrator that a certificate is to be renewed.

13. A method according to claim 1, wherein said instructions are further executable to achieve the functions of:

following said receiving a certificate signed by a certificate authority, informing an administrator of that renewed certificate;

prior to said installing, requesting approval to install a renewed certificate received from a certificate authority; and

receiving, in response to a request for approval, an indication from an administrator that a renewed certificate is to be installed.

14. A method according to claim 1, wherein said instructions are further executable to store a received certificate signed by a certificate authority to a backup storage device.
