Verify peer cert function for better man in the middle prevention (#746)
* verify peer cert function for better man in the middle prevention * publish cert chain hash generation algorithm * added calculation of certificate hash as separate command and tlsping, use base64 to represent fingerprint to align with jsonPb * apply coding style * added test case for pinned certificates * refactored cert pin * pinned cert test * added json loading of the PinnedPeerCertificateChainSha256 * removed tool to prepare for v5 * Add server cert pinning for Xtls Change command "xray tls certChainHash" to xray style Co-authored-by: Shelikhoo <xiaokangwang@outlook.com>
