I was "auditing" the SSL certificate that I'm using for IHS, specifically the signature algorithm.
So I have a single certificate in the key store: -
/opt/IBM/HTTPServer/bin/gskcapicmd -cert -list -db /opt/IBM/HTTPServer/APIC/ssl/keystore.kdb -pw passw0rd
which I validated as follows: -
/opt/IBM/HTTPServer/bin/gskcapicmd -cert -details -db /opt/IBM/HTTPServer/APIC/ssl/keystore.kdb -pw passw0rd -label wlpn.uk.ibm.com
Label : wlpn.uk.ibm.com

Notice that this has a SHA1 signature algorithm ( SigAlg ), which is potentially less secure than SHA2: -
I also used OpenSSL to check / validate the SigAlg: -
openssl s_client -connect localhost:8443 </dev/null|openssl x509 -text -noout

Therefore, I wanted to delete and re-issue the self-signed certificate, using a stronger SHA2 SigAlg.
This is what I did: -
Stop IHS
/opt/IBM/HTTPServer/bin/apachectl -k stop -f /opt/IBM/HTTPServer/APIC/conf/httpd.conf
Delete the Self-Signed Certificate
/opt/IBM/HTTPServer/bin/gskcapicmd -cert -delete -db /opt/IBM/HTTPServer/APIC/ssl/keystore.kdb -pw passw0rd -label wlpn.uk.ibm.com
Create a new Self-Signed Certificate
/opt/IBM/HTTPServer/bin/gskcapicmd -cert -create -db /opt/IBM/HTTPServer/APIC/ssl/keystore.kdb -pw passw0rd -sigalg SHA256WithRSA -size 2048 -dn cn=wlpn.uk.ibm.com -san_dnsname wlpn.uk.ibm.com -label wlpn.uk.ibm.com -default_cert yes
- Note that I also included the -san_dnsname parameter to set the Subject Alternate Name (SAN) field - this is to "reassure" Google Chrome that warns against certificates where this field is not set
Validate
/opt/IBM/HTTPServer/bin/gskcapicmd -cert -list -db /opt/IBM/HTTPServer/APIC/ssl/keystore.kdb -pw passw0rd

Of course, this won't satisfy some of our more fussy browsers/extensions - SSLSleuth in Firefox only gives us 5.3 out of 10: -
One can mitigate this by reducing the number of ciphers presented by IHS, and restricting it to use ciphers that offer Perfect Forward Secrecy (PFS), as follows: -
LoadModule ibm_ssl_module modules/mod_ibm_ssl.so
Listen 8443
<VirtualHost *:8443>
SSLProtocolEnable TLSv12
SSLProtocolDisable SSLv2 SSLv3 TLSv10 TLSv11
SSLCipherSpec ALL NONE
SSLCipherSpec TLSv12 TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
SSLCipherSpec TLSv12 TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
SSLEnable
</VirtualHost>
KeyFile /opt/IBM/HTTPServer/APIC/ssl/keystore.kdb

After a restart, SSLSleuth now gives us a reasonable 9 out of 10: -
and Google Chrome is moderately happy: -
It's major objection, hence the This page is not secure (broken HTTPS) message, is that we're using a self-signed certificate :-(
Final thought - I've mentioned this before, but will mention it again - one can dump out the IHS SSL configuration, and get an summary of what we have: -
/opt/IBM/HTTPServer/bin/apachectl -DDUMP_SSL_CONFIG -f /opt/IBM/HTTPServer/APIC/conf/httpd.conf
SSL configuration:
