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.
