Class AirPlayHapPairVerifyProcedure

Namespace

AppleTvControlLibrary.Mrp.AirPlay.Auth

Assembly

AppleTvControlLibrary.Mrp.dll

Verify a previously-paired device is allowed to establish an AirPlay 2 control connection, and derive the resulting session encryption keys.

Remarks

Only the HAP pair-verify path is ported here (the path used by tvOS Apple TVs); pyatv's legacy and transient AirPlay auth variants are out of scope for MRP-over-AirPlay tunnel support (see auth/init.py — line 84-98 as of pyatv 0.18.0: HAP credentials are required for Apple TV once tvOS >= 13).

Parameters

http HttpConnection

The AirPlay control connection.

srp SrpAuthHandler

The SRP handler used for key agreement.

credentials HapCredentials
