Detailed Description

Signature_Algorithms_Cert for TLS 1.3 (RFC 8446)

RFC 8446 4.2.3 TLS 1.3 provides two extensions for indicating which signature algorithms may be used in digital signatures. The "signature_algorithms_cert" extension applies to signatures in certificates, and the "signature_algorithms" extension, which originally appeared in TLS 1.2, applies to signatures in CertificateVerify messages.

RFC 8446 4.2.3 TLS 1.2 implementations SHOULD also process this extension.

Member Function Documentation

empty()

bool Botan::TLS::Signature_Algorithms_Cert::empty ( ) const

inlineoverridevirtual

Predicate if a TLS extension should be included or not

Returns

true if this extension should be encoded, otherwise false

Implements Botan::TLS::Extension.

Definition at line 319 of file tls_extensions.h.

{ return m_schemes.empty(); }

is_implemented()

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

inlinevirtualinherited

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()

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

overridevirtual

Serialize a TLS extension

Parameters

whoami

which peer we are acting as in the protocol

Returns

serialized binary for the extension

Implements Botan::TLS::Extension.

Definition at line 741 of file tls_extensions.cpp.

                                                                               {
