Increase support/make configurable Azure Bastion https client SSH ciphers

Hello all,

We have an encryption standard that holds chacha20-poly1305@openssh.com as the only cipher that can be used.

I now need to seek a security exception to utilize aes256-ctr as a cipher for SSH in order to support the Azure Bastion https client SSH client.

Is there a feature I'm missing that allows me to configure ciphers for the Azure Bastion https client SSH client? Or is there an ETA on this feature?

Thanks,

Matt

    Hi @Matthew Brown

    Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.

    ChaCha20-Poly1305 PolyChacha ciphers are supported by Windows and can be enabled in scenarios where customers control the OS.
