Which SHA* Certificate Algorithms are supported by RTC?

Corey Jacobs (642239) | asked Oct 06 '15, 7:54 p.m.
I'm using JTS/RTC/RQM 4.0.7 with Tomcat 7.0.61 installed on Windows 2008 Server R2 Enterprise VM.  
I'm receiving failing scans with the certificate due to SHA1withRSA algorithm being used.  The failing scan complains: The remote service uses an SSL certificate chain that has been signed using a cryptographically weak hashing algorithm (e.g. MD2, MD4, MD5, or SHA1). 

I made a CSR through ikeyman on the Windows Server machine, with SHA256withRSA and 2048 for key size.  I used the IBM Internal CA for my certificates.   I successfully receive the DER/JKS/cert files and import them through ikeyman.  I also made sure to update the tomcat\conf\server.xml file to  point to this new jks file.  However when starting up the Rational Applications and going to the urls, I have problems with the apps with both firefox & chrome:
An error occurred during a connection to jts:9446. Certificate type not approved for application. (Error code: sec_error_inadequate_cert_type)

Does JTS/RTC/RQM support SHA256withRSA algorithm for certificates?  If not would any of the following (SHA2WithECDSA, SHA3WithECDSA,,SHA5WithECDSA, SHA284WithRSA, SHA512WithRSA) work?  I can also list the ciphers used in server.xml file if need be as well.

That should be a Tomcat issue rather than CLM. The error occurred when your browser tried to established an SSL connection with the Tomcat server, so the direction of your research should be a bit different. It may be similar to this:

If in the jts.log or ccm.log file, you see connection errors that they cannot connect to each other, then the problem lies in the product itself.
