A TLS Banner Grabber, in Go
docker build . -t baykovr/zgrab:latest
docker-compose build
This dockerized version relies on an input file rather than piping over stdin. We expose /var/lib/zgrab as a possible volume mount point for input file storage, a sample file is included in zinput/host.sample ; example invocations follow below.
docker run -v $GOPATH/src/github.com/baykovr/zgrab/zinput:/var/lib/zgrab baykovr/zgrab:latest --tls --port 443 --http="/" -input-file /var/lib/zgrab/host.sample
Alternative, modify the command section of docker-compose, invoke
docker-compose up
You will need to have a valid $GOPATH set up, for more information about $GOPATH, see https://golang.org/doc/code.html.
Once you have a working $GOPATH, run:
go get github.com/baykovr/zgrab
This will install zgrab under $GOPATH/src/github.com/baykovr/zgrab
$ cd $GOPATH/src/github.com/baykovr/zgrab
$ go build
./zgrab --help
$ zmap -p 443 --output-fields=* | ztee results.csv | zgrab --port 443 --tls --http="/" --output-file=banners.json
zgrab requires go version of at least 1.6. Please note that this is newer than the version included in Ubuntu 14.04 apt repository. You can install ztee from ZMap Github repository at https://github.com/zmap/zmap.
If you are using ZGrab code in another Go program, import ZGrab using gopkg.in. ZGrab tends to be very unstable, API's may break at any time, so be sure to vendor ZGrab.
