certificates from pcap files or network interfaces\n * fingerprints TLS client/server interactions with ja3/ja3s\n * fingerprints TLS interactions with TLSH fuzzy hashing\n * write certificates in a folder\n * export in JSON to files, or stdout\n\n# Use\nThis project is currently in development and is subject to change, check the list of issues.\n\n## Compile from source\n### requirements\n * git\n * golang \u003e= 1.5\n * libpcap\n\n``` shell\n#apt install golang git libpcap-dev\n```\n### Go get\n\n``` shell\n$go get github.com/D4-project/sensor-d4-tls-fingerprinting\n$cd $GOPATH/github.com/D4-project/sensor-d4-tls-fingerprinting\n$\n```\nA \"sensor-d4-tls-fingerprinting\" compiled for your architecture should then be in $GOPATH/bin\nAlternatively, use make to compile arm/linux or amd64/linux\n\n## How to use\n\nRead from pcap:\n``` shell\n$ ./d4-tlsf-amd64l -r=file \n\n```\nRead from interface (promiscious mode):\n``` shell\n$ ./d4-tlsf-amd64l -i=interface \n\n```\nWrite x509 certificates to folder:\n``` shell\n$ ./d4-tlsf-amd64l -w=folderName \n```\nWrite output json inside folder\n\n``` shell\n$ ./d4-tlsf-amd64l -j=folderName \n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fd4-project%2Fsensor-d4-tls-fingerprinting","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fd4-project%2Fsensor-d4-tls-fingerprinting","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fd4-project%2Fsensor-d4-tls-fingerprinting/lists"}
