# SSLGetSupportedCiphers(_:_:_:) Determines the values of the supported cipher suites. ``` func SSLGetSupportedCiphers(_ context: SSLContext, _ ciphers: UnsafeMutablePointer, _ numCiphers: UnsafeMutablePointer) -> 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(_:_:)`](/documentation/Security/SSLGetNumberSupportedCiphers(_:_:)) function. `numCiphers` Points to the number of supported cipher suites that you want returned. Before calling, retrieve this value by calling the [`SSLGetNumberSupportedCiphers(_:_:)`](/documentation/Security/SSLGetNumberSupportedCiphers(_:_:)) function. ## Return Value A result code. See [Secure Transport Result Codes](/documentation/Security/secure-transport-result-codes). If the supplied buffer is too small, [`errSSLBufferOverflow`](/documentation/Security/errSSLBufferOverflow) is returned. ## Discussion All the supported cipher suites are enabled by default. Use the [`SSLSetEnabledCiphers(_:_:_:)`](/documentation/Security/SSLSetEnabledCiphers(_:_:_:)) function to enable a subset of the supported cipher suites. Use the [`SSLGetEnabledCiphers(_:_:_:)`](/documentation/Security/SSLGetEnabledCiphers(_:_:_:)) function to determine which cipher suites are currently enabled. --- Copyright © 2026 Apple Inc.
