PH59794: TLS HANDSHAKE ISSUE WITH SAF DB RSA SOFTWARE KEY WITH IBMJCEHYBRID AND IBMJCECCA

APAR status

• Closed as program error.

Error description

• Error Message: A TLS handshake error can happen when using
  IBMJCEHYBRID as the first security provider and using a
  JCECCARACFKS keystore with the cert RSA private key stored in
  the SAF database versus ICSF PKDS.
  .
  Stack Trace: IBMJCEHybridException: Object state does not permit
  failover.
  Exception#0 java.security.InvalidKeyException: Key is not

Local fix

• Using the RSA software keys in the ICSF PKDS or RACF and loading
  them using JCEHYBRIDRACFKS or JCECCARACFKS can resolve the
  issue.
  

Problem summary

• A TLS handshake error can happen when using IBMJCEHYBRID as the
  first security provider and using a JCECCARACFKS keystore with
  the cert RSA private key stored in the SAF database versus ICSF
  PKDS.
  

Problem conclusion

• The RSA Software keys are translated properly to be processed by
  IBMJCEHYBRID to proceed with the TLS handshake.
