    SSL ports fail to start when IBMJDK 8.0.6.25 and IBMJCEFIPS
    provider is used.
    

Problem conclusion

  • WebSphere will disable the RSAPSS algorithm programmatically if
    FIPS 140-2 is enabled in the configuration and IBMJCEFIPS
    provider is used.
    
    To check if FIPS is enabled in WebSphere's configuration, from
    the adminconsole, security -> SSL certificate and key
    management
    > Manage FIPS
    and check if FIPS is enabled.
    
    or in security.xml, see if "com.ibm.security.useFIPS" is set to
    true (enabled)
    
    
    The fix for this APAR is targeted for inclusion in
    8.5.5.20 and 9.0.5.7. For more information, see
