Problem summary


    

  • With APAR IT18692 cipherspecs TLS_RSA_WITH_DES_CBC_SHA,
TLS_RSA_WITH_NULL_SHA256 and TLS_RSA_WITH_3DES_EDE_CBC_SHA have
become depricated.

    



Problem conclusion


    

  • The WebSphere MQ product code has been changed as such that
there is now a new class of WEAK cipherspecs alongside the
depricated SSLv3 cipherspecs.
An alternative way of SSL configuration, using the queue
manager's mqs.ini file, has also been implemented to make the
operation on HP NonStop more similiar to other MQ platforms.
The SSLUpdate document has been revised to accommodate these
product changes.
