Using Server Administrator 65
•The SSL Encryption field specifies the encryption levels for the
secured HTTPS sessions. The available encryption levels include
Auto
Negotiate
and 128-bit or higher .
•
Auto Negotiate — Allows connection from browser with any
encryption strength. The browser auto negotiates with the Server
Administrator web server and uses the highest available
encryption level for the session. Legacy browsers with weaker
encryption can connect to the Server Administrator.
•
128-bit or higher — Allows connections from browsers with
128-bit or higher encryption strength. One of the following cipher
suites is applicable based on the browser for any established
sessions:
SSL_RSA_WITH_RC4_128_SHA
SSL_RSA_WITH_RC4_128_MD5
SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA
TLS_DHE_RSA_WITH_AES_128_CBC_SHA
SSL_RSA_WITH_3DES_EDE_CBC_SHA
TLS_RSA_WITH_AES_128_CBC_SHA
TLS_DHE_DSS_WITH_AES_128_CBC_SHA
SSL_DHE_DSS_WITH_3DES_EDE_CBC_SHA
• Key Signing Algorithm — Displays the supported signing algorithms.
Select an algorithm from the drop down list. 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
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.
NOTE: Restart the Server Administrator web server for the changes to take
effect.
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.
