h2t 是一个简单的工具，用于帮助系统管理员强化其网站。
截至目前，h2t 可以检查网站头部，并推荐如何改进。
$ git clone https://github.com/gildasio/h2t
$ cd h2t
$ pip install -r requirements.txt
$ ./h2t.py -h
……或者通过 Docker 方式：
$ git clone https://github.com/gildasio/h2t
$ cd h2t
$ docker build -t h2t .
$ docker run --rm h2t -h
你也可以将 alias h2t='docker run --rm h2t' 放入某个文件（例如 ~/.bash_aliases），然后像这样运行：
$ h2t -h
h2t 包含子命令：list 和 scan。
$ ./h2t.py -h
usage: h2t.py [-h] {list,l,scan,s} ...

be used in scan subcommand -H option)
scan (s) scan url to hardening headers
optional arguments:
-h, --help show this help message and exit
list 子命令列出 h2t 中收录的所有头部，并可以显示有关信息，如描述、更多信息的链接以及操作方法。
$ ./h2t.py list -h

[-a | -H HEADERS [HEADERS ...]]
optional arguments:
-h, --help show this help message and exit
-p PRINT [PRINT ...], --print PRINT [PRINT ...]
a list of additional information about the headers to
print. For now there are two options: description and
refs (you can use either or both)
-B, --no-banner don't print the h2t banner
-a, --all list all available headers [default]
-H HEADERS [HEADERS ...], --headers HEADERS [HEADERS ...]
a list of headers to look for in the h2t catalog
scan 子命令对网站执行扫描，查看其头部。
$ ./h2t.py scan -h
usage: h2t.py scan [-h] [-v] [-a] [-g] [-b] [-H HEADERS [HEADERS ...]]
[-p PRINT [PRINT ...]]
[-i IGNORE_HEADERS [IGNORE_HEADERS ...]] [-B] [-E] [-n]
[-u USER_AGENT] [-r | -s]
url
positional arguments:
url url to look for
optional arguments:
-h, --help show this help message and exit
-v, --verbose increase output verbosity: -v print response headers,
-vv print response and request headers
-a, --all scan all cataloged headers [default]
-g, --good scan good headers only
-b, --bad scan bad headers only
-H HEADERS [HEADERS ...], --headers HEADERS [HEADERS ...]
scan only these headers (see available in list sub-
command)
-p PRINT [PRINT ...], --print PRINT [PRINT ...]
a list of additional information about the headers to
print. For now there are two options: description and
refs (you can use either or both)
-i IGNORE_HEADERS [IGNORE_HEADERS ...], --ignore-headers IGNORE_HEADERS [IGNORE_HEADERS ...]
a list of headers to ignore in the results
-B, --no-banner don't print the h2t banner
-E, --no-explanation don't print the h2t output explanation
