Why Am I Prompted to Upgrade My SSH Feature?

Some insecure encryption algorithms have been removed from the SSH function of CodeArts Repo.

Key Exchange (KEX) and Message Authentication Code (MAC) no longer support the following algorithms:

KEX:

  • diffie-hellman-group18-sha512
  • diffie-hellman-group-exchange-sha1
  • diffie-hellman-group-exchange-sha256

MAC:

  • hmac-md5
  • hmac-md5-96
  • hmac-sha1-etm@openssh.com
  • hmac-sha1-96-etm@openssh.com
  • hmac-md5-etm@openssh.com
  • hmac-md5-96-etm@openssh.com
  • umac-64@openssh.com
  • umac-128@openssh.com

Upgrade your code commit tool (such as Git Bash, Eclipse, and IntelliJ IDEA) to the latest version. By default, the new version uses algorithms that are more secure.

If you have any questions, contact technical support.
