How To
Summary
To help with the migration, L3 is allowing L2 to modify the Java™ security package to enable SHA1.
Removing SHA1 is a workaround, not a solution.
Customer needs to continue moving to certificates on their App Connect Professional appliance and their endpoints that use SSL.
Customer will have to do this update manually with L2 Assistance after any upgrade interim fix.
Steps
With Studio not running
On windows file manager navigate to the studio install dir.
for example: C:\Program Files\IBM\App Connect Studio 754 Base\security
copy java.security.override so you have a backup
edit with notepad or another test editor java.security.override
Change the following line
jdk.tls.disabledAlgorithms=SSLv3, TLSv1, RC4, DES, MD5withRSA, DH keySize < 1024, DESede, \
EC keySize < 224, 3DES_EDE_CBC, anon, NULL, SHA1, CBC
to
jdk.tls.disabledAlgorithms=SSLv3, TLSv1, RC4, DES, MD5withRSA, DH keySize < 1024, DESede, \
EC keySize < 224, 3DES_EDE_CBC, anon, NULL
