Customer ECDSA host keys accepted?

We have customers that are using ECDSA host keys on their servers, and they will not change this. So we have to accept this key and have it work in our SI SSH profile.

    Version 6.0 supports ECDSA algorithms

    https://www.ibm.com/support/knowledgecenter/SS3JSW_6.0.0/integrating/integrating/integrator/SFTP_Client_Begin_Session_svc.html

    You cannot configure the SSH Key Exchange algorithms to be used with SFTP in the Sterling B2B Integrator UI. To select strong SSH Key Exchange algorithms, specify the values to be used in SSHKeyExchangeAlgList in the security.properties file. For example, SSHKeyExchangeAlgList=diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1,diffie-hellman-group14-sha1. You can verify the algorithm used in the SFTP Client Begin Session service status report.

    Sterling B2B Integrator also supports the following key exchange algorithms:
    • ecdh-sha2-nistp256
    • ecdh-sha2-nistp384
    • ecdh-sha2-nistp521
