19*6236dae4SAndroid Build Coastguard WorkerDo not work around a security flaw in the TLS1.0 protocol known as BEAST. If
20*6236dae4SAndroid Build Coastguard Workerthis option is not used, the TLS layer may use workarounds known to cause
21*6236dae4SAndroid Build Coastguard Workerinteroperability problems with some older server implementations.
22*6236dae4SAndroid Build Coastguard Worker
23*6236dae4SAndroid Build Coastguard WorkerThis option only changes how curl does TLS 1.0 and has no effect on later TLS
24*6236dae4SAndroid Build Coastguard Workerversions.
25*6236dae4SAndroid Build Coastguard Worker
26*6236dae4SAndroid Build Coastguard Worker**WARNING**: this option loosens the TLS security, and by using this flag you
27*6236dae4SAndroid Build Coastguard Workerask for exactly that.
