Function

SSLGetSupportedCiphers(_:_:_:)

Determines the values of the supported cipher suites.

Declaration

func SSLGetSupportedCiphers(_ context: SSLContext, _ ciphers: UnsafeMutablePointer<SSLCipherSuite>, _ numCiphers: UnsafeMutablePointer<Int>) -> OSStatus

Parameters

context

An SSL session context reference.

ciphers

On return, points to the values of the supported cipher suites. Before calling, you must allocate this buffer using the number of supported cipher suites retrieved from a call to the SSLGetNumberSupportedCiphers(_:_:) function.

numCiphers

Points to the number of supported cipher suites that you want returned. Before calling, retrieve this value by calling the SSLGetNumberSupportedCiphers(_:_:) function.

Return Value

A result code. See Secure Transport Result Codes. If the supplied buffer is too small, errSSLBufferOverflow is returned.

Discussion

All the supported cipher suites are enabled by default. Use the SSLSetEnabledCiphers(_:_:_:) function to enable a subset of the supported cipher suites. Use the SSLGetEnabledCiphers(_:_:_:) function to determine which cipher suites are currently enabled.
