NOTE: The 128-bit or Higher option does not allow connections from browsers with lower SSL encryption
strength, such as 40 bit and 56 bit.
● Key Signing Algorithm (For Self Signed Certificate) — Allows you to select a supported signing algorithm. If you
select either SHA 512 or SHA 256, ensure that your operating system/browser supports this algorithm. If you select
one of these options without the requisite operating system/browser support, Server Administrator displays a cannot
display the webpage error. This field is meant only for Server Administrator auto-generated self-signed certificates.
The drop-down list is grayed out if you import or generate new certificates into Server Administrator.
● The Java Runtime Environment — Allows you to select the one of the following options:
● Bundled JRE — Enables use of the JRE provided along with the System Administrator.
● System JRE — Enables use of the JRE installed on the system. Select the required version from the drop-down list.
NOTE: If the JRE does not exist on the system on which Server Administrator is running, the JRE provided with the
Server Administrator is used.
NOTE: If the encryption level is set to 128-bit or Higher, you can access or modify the Server Administrator settings
using a browser with the same or higher encryption levels.

NOTE: You must restart the Server Administrator web server for the changes to take effect.
X.509 Certificate Management
NOTE: You must be logged in with Administrator privileges to perform certificate management.
Web certificates are necessary to ensure the identity of a remote system and ensure that information exchanged with the
remote system are not viewed or changed by others. To ensure system security, it is recommended that:
● You generate a new X.509 certificate, reuse an existing X.509 certificate or import a certificate chain from a Certification
Authority (CA).
● All systems that have Server Administrator installed have unique host names.
To manage X.509 certificates through the Preferences home page, click General Settings, click the Web Server tab, and
click X.509 Certificate.
The following are the available options:
●
Generate a new certificate — Generates a new self-signed certificate used for SSL communication between the server
running Server Administrator and the browser.
NOTE:
When using a self-signed certificate, most web browsers display an untrusted warning as the self-signed
certificate is not signed by a Certificate Authority (CA) trusted by the operating system. Some secure browser settings
can also block the self-signed SSL certificates. The OMSA web GUI requires a CA-signed certificate for such secure
browsers.
● Certificate Maintenance — Allows you to generate a Certificate Signing Request (CSR) containing all the certificate
information about the host required by the CA to automate the creation of a trusted SSL web certificate. You can retrieve
the necessary CSR file either from the instructions on the Certificate Signing Request (CSR) page or by copying the entire
text in the text box on the CSR page and pasting it in the CA submit form. The text must be in the Base64–encoded format.
NOTE:
You also have an option to view the certificate information and export the certificate that is being used in the
Base64–encoded format, which can be imported by other web services.
● Import certificate chain — Allows you to import the certificate chain (in PKCS#7 format) signed by a trusted CA. The
certificate can be in DER or Base64-encoded format.
