sec_protocol_metadata_access_supported_signature_algorithms(_:_:)

Declaration

func sec_protocol_metadata_access_supported_signature_algorithms(_ metadata: sec_protocol_metadata_t, _ handler: @escaping (UInt16) -> Void) -> Bool

Parameters

• metadata:

  A sec_protocol_metadata_t instance.

• handler:

  A block to invoke one or more times, once per signature algorithm advertised by the peer. Each signature_algorithm is a TLS SignatureScheme codepoint (the on-the-wire 2-byte value) from the IANA “TLS SignatureScheme” registry — see RFC 8446 §4.2.3.

Return Value

Returns true if the supported signature list was accessible, false otherwise.

Discussion

Get the signature algorithms supported by the peer. Clients may call this in response to a challenge block.
