Member Function Documentation

empty()

virtual bool Botan::TLS::Extension::empty ( ) const

pure virtual

Predicate if a TLS extension should be included or not

Returns

true if this extension should be encoded, otherwise false

Implemented in Botan::TLS::Application_Layer_Protocol_Notification, Botan::TLS::Certificate_Authorities, Botan::TLS::Certificate_Status_Request, Botan::TLS::Certificate_Type_Base, Botan::TLS::Cookie, Botan::TLS::EarlyDataIndication, Botan::TLS::Encrypt_then_MAC, Botan::TLS::Extended_Master_Secret, Botan::TLS::Key_Share, Botan::TLS::PSK, Botan::TLS::PSK_Key_Exchange_Modes, Botan::TLS::Record_Size_Limit, Botan::TLS::Renegotiation_Extension, Botan::TLS::Server_Name_Indicator, Botan::TLS::Session_Ticket_Extension, Botan::TLS::Signature_Algorithms, Botan::TLS::Signature_Algorithms_Cert, Botan::TLS::SRTP_Protection_Profiles, Botan::TLS::Supported_Groups, Botan::TLS::Supported_Point_Formats, Botan::TLS::Supported_Versions, and Botan::TLS::Unknown_Extension.

is_implemented()

virtual bool Botan::TLS::Extension::is_implemented ( ) const

inlinevirtual

Predicate if the extension is known/implemented

Note

this exists primarily to support unknown extension handling and doesn't need to be overridden even in the custom extension case.

Returns

true if this extension is known

Reimplemented in Botan::TLS::Unknown_Extension.

Definition at line 113 of file tls_extensions.h.

{ return true; }

serialize()

virtual std::vector< uint8_t > Botan::TLS::Extension::serialize ( Connection_Side whoami ) const

pure virtual

Serialize a TLS extension

Parameters

whoami

which peer we are acting as in the protocol

Returns

serialized binary for the extension

Implemented in Botan::TLS::Application_Layer_Protocol_Notification, Botan::TLS::Certificate_Authorities, Botan::TLS::Certificate_Status_Request, Botan::TLS::Certificate_Type_Base, Botan::TLS::Cookie, Botan::TLS::EarlyDataIndication, Botan::TLS::Encrypt_then_MAC, Botan::TLS::Extended_Master_Secret, Botan::TLS::Key_Share, Botan::TLS::PSK, Botan::TLS::PSK_Key_Exchange_Modes, Botan::TLS::Record_Size_Limit, Botan::TLS::Renegotiation_Extension, Botan::TLS::Server_Name_Indicator, Botan::TLS::Session_Ticket_Extension, Botan::TLS::Signature_Algorithms, Botan::TLS::Signature_Algorithms_Cert, Botan::TLS::SRTP_Protection_Profiles, Botan::TLS::Supported_Groups, Botan::TLS::Supported_Point_Formats, Botan::TLS::Supported_Versions, and Botan::TLS::Unknown_Extension.

type()

virtual Extension_Code Botan::TLS::Extension::type ( ) const

pure virtual

Return TLS extension code

Returns

code number of the extension
