Overriding HSP Local Listener Certificates
By default, the signing certificate configured on the Certificates tab of the Local Listener panel will be the certificate used to authenticate messages sent to your trading partner. See Configuring certificates for Local Listener.
Use Override Local Listener Certificates to select alternate certificates for signing and decrypting messages with this trading partner. If you override the default certificates, do not forget to export and exchange these alternate certificates with your trading partner.
