I have seen conflicting answers to this question. How would I activate a DTLS session using InitializeSecurityContext?
回答1:
DTLS is present in Windows 8 and later.
When creating your credentials you need to the SCHANNEL_CRED grbitEnabledProtocols to include SP_PROT_DTLS1_0_SERVER or one of the other DTLS values from schannel.h
You then need to select the correct requirements for the "required attributes" when creating your context (things like ISC_REQ_DATAGRAM from sspi.h).
See technet for some more information.
