|Since version 6 BCS, when acting as a BCS client, might use a new method for login when being connected via WebSockets. It is an HMAC authorization, which has the advantage that the password is never transferred via network, only a hash value. This method only works if both BCS computers use the same DigaSystem registry (Global.par/Rights.par). Therefore, you can use this parameter to choose a different login method for special situations, like when one of the BCS computers use a different registry as the other one. The following options are allowed:
- HMAC: Use an HMAC based authorization.
- RC5: Cypher the password with the RC5 algorithm. This is the classical/old method used by old version and/or SeplProtocol connections. The password is transferred via network.
- AUTO: This is the default. BCS will choose the right method automatically, which is: HMAC for a WebSocket connection and RC5 otherwise.
BCS will only use the HMAC method if you specify a DigaSQL user for BCS itself in key BroadcastServer\
