Description:

Definition of URIMAP in CTS with a Certificate gets CICS message error as follows:

DFHAM4928 E MYCICS 425 Install of URIMAP MY-URIMAP failed because the specified certificate does not have a private key.

Solution:

The URIMAP definition:

  DEFINE URIMAP(MY-URIMAP) GROUP(WEBGRP1)
   STATUS(ENABLED) USAGE(CLIENT) SCHEME(HTTPS) PORT(NO)
   HOST(my.website.com) PATH(/service/SOAP/SILOSGW/MYCONSUMER)
   SOCKETCLOSE(0) ANALYZER(NO)
   CIPHERS(050435363738392F303132330A1613100D0915120F0C03060201)
   CERTIFICATE(MYCERT001) AUTHENTICATE(NO) REDIRECTTYPE(NONE)
   DEFINETIME(12/05/23 16:08:07) CHANGETIME(12/05/23 16:08:07)
   CHANGEUSRID(CUSER001) CHANGEAGENT(CSDBATCH) CHANGEAGREL(0670)

In this case the certificate MYCERT001 must have a PRIVATE key.

The client sends a CertificateVerify message, which is a signature over the previous handshake messages using the client's certificate's private key. This signature can be verified by using the client's certificate's public key. This lets the server know that the client has access to the private key of the certificate and thus owns the certificate.

So having a client certificate private key is fundamental to a successful SSL handshake.
