There are a number of deprecations around TLS that affect our build support. I am investigating what's the best replacement for those.

@snicoll can you give me more details? I am new to this and I want to work on this.

@Shivam1-123 thanks for the offer but I am already assigned on the issue. I am afraid the changes are pretty advanced so it might not be a good pick for a newcomer.

@snicoll Okay Thank you clearing that out.
