# sslCipherSuites

The set of allowed cipher suites when negotiating TLS.

## Declaration

```swift
var sslCipherSuites: Set<NSNumber>? { get set }
```

## Discussion

Discussion Values for cipher suites are defined in <Security/CipherSuite.h>. These values should be wrapped as NSNumber objects in a set. If this property is set to nil, the default cipher suites will be used.
