PI87414: AFTER DELETING THE EXISTING DEFAULT CERTIFICATES, THE NEWLY CREATED DEFAULT CERTIFICATES ARE USING SHA1

Fixes are available

APAR status

Closed as program error.

Error description

When you delete the *.p12 files in the
<PROFILE_ROOT>\config\cells\<CELLNAME>\nodes\<NODENAME>
directory, start WebSphere Application Server, the newly
created certificates use "SHA1withRSA" as signature
algorithm whereas "SHA256withRSA" would be expected.

Local fix

Run the convertCertForSecurityStandard AdminTask to convert the
signature algorithm from SHA1 to SHA256; see
https://developer.ibm.com/answers/questions/206339/how-to-replac
e-websphere-default-certificate-from.html

Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server                                      *
****************************************************************
* PROBLEM DESCRIPTION: Recovered keystore and truststore       *
*                      contain certificate with SHA1 algorithm *
*                      instead of SHA256                       *
****************************************************************
* RECOMMENDATION:  It is recommended to always keep backup     *
*                  copy                                        *
*                  of the keystore and truststore.             *
****************************************************************
WebSphere recovers keystore and truststore files if they are
not found at server startup.  This function is for
serviceability purpose and not officially supported but many
customers familiar with it and found handy.
The reported issue is, recovered keystore and truststore still
include certificates with SHA1 algorithm although default
certificates have been updated to SHA256.

Problem conclusion

The bug was fixed so that recovered keystore and truststore
contain certificates with SHA256 algorithm.

The fix for this APAR is currently targeted for inclusion in
fix pack 8.5.5.14 and 9.0.0.7 Please refer to the Recommended
Updates
page for delivery information:
http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980

Temporary fix

Replace the certificates with newly created SHA256 certificates.
