In case you need to disable a particular SSL cipher, it can be done by adjusting it in RAS Console > Farm > Gateways > right-click on a Gateway > Properties > SSL/TLS > Cipher Strength.
For example, you want to use Medium Cipher Strength, excluding the TLS_RSA_WITH_3DES_EDE_CBC_SHA cipher.
Here how it's done:
Copy the Medium Cipher string:
- Add the following after !EXP: - !DES-CBC3-SHA:
End result should be like that:
In general, you should get the OpenSSL name of the cipher suite, and insert it into a string with an "!" before the name. OpenSSL name list for cipher suites is available here.
