Hi,
Our company uses the Co:Z software to transfer files from the mainframe to external vendors. We have version “CoZBatchÝN¨: version: 4.5.1 2017-10-09”
One of our new vendors SFTP site now enforces a new key exchange “diffie-hellman-group-exchange-sha256” and a mac algorithms of “hmac-sha2-256”.
Will the version we have of Co:Z support this change?

Re: Co:Z algorithms and key exchanges
Co:Z SFTP uses z/OS OpenSSH for its underlying ssh connection.
KEX, Cipher, MAC, and key algorithm support is provided by OpenSSH
Refer to the z/OS OpenSSH User's Guide for supported algorithms.
Also, there are these commands:
ssh -Q kex # display supported kex algorithms
ssh -Q mac # display supported mac algorithms
