Function hook is also an approach to network data analysis. Public key pinning (https://shtrm.ru/forum/?serial=9058) is designed to give web site operators the means to restrict which CAs can issue certificates for their web sites. If the data is encrypted with a private key, only the corresponding public key can be used to decrypt (and vise versa). On MITM / Signature chains. DTLS protocol is based on the stream-oriented Transport Layer Security (TLS) protocol and is intended to provide similar security guarantees.
