SHA256 and more?

[Neustradamus]

Can you add the SHA256 support?

Please note:

• RFC8489: Session Traversal Utilities for NAT (STUN): https://tools.ietf.org/html/rfc8489
• RFC8760: The Session Initiation Protocol (SIP) Digest Access Authentication Scheme: https://tools.ietf.org/html/rfc8760
• https://msdn.microsoft.com/en-us/library/dd949398(v=office.12).aspx

SHA-256
SHA-512/256

Do you have a business need for all these asks where such extensions would enable a deployment that is otherwise impossible? Or is this more of a "it would cool if you did this"?
