Django OpenSSL setting

INSTALL openssl

$ openssl version                                     
OpenSSL 1.0.2s  28 May 2019

version이 나오지않으면 설치가 되어있지 않은 것이므로 설치가 필요하다.

homebrew로 설치하기

$ brew install openssl

Key 생성하기

$ openssl genrsa 1024 > {{keyname}}.key
Generating RSA private key, 1024 bit long modulus
..................+++++
......+++++
e is 65537 (0x10001)

Cert 파일 생성하기

$ openssl req -new -x509 -nodes -sha256 -days 365 -key {{keyname}}.key > {{certname}}.cert

You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:
State or Province Name (full name) [Some-State]:
Locality Name (eg, city) []:
Organization Name (eg, company) [Internet Widgits Pty Ltd]:
Organizational Unit Name (eg, section) []:
Common Name (e.g. server FQDN or YOUR name) []:
Email Address []:

이때 .key 파일과 .cert 파일은 manage.py 파일과 같은 depth에 생성한다.

인증서는 설치후에 키체인관리에서 이 인증서 사용 시 항상 신뢰로 변경해준다.

Install django-sslserver

$ pip install django-sslserver

이때 외부 네트워크 접속이 자유롭지 못한 네트워크 (회사 네트워크 등)에서는 SSL 인증서 문제 등으로 pip를 통한 라이브러리 다운 및 설치가 되지 않을 수 있다.

pip의 옵션 중 --trusted-host 옵션을 사용해 라이브러리를 설치하는 url을 옵션으로 지정 후 설치해주면된다.

$ pip --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host pypi.org install django-sslserver

매번 --trusted-host 옵션을 추가하기 귀찮은 경우에는 .zshrc에 alias 설정을 하면된다.

alias pip='pip --trusted-host pypi.org --trusted-host files.pythonhosted.org --trusted-host pypi.org'

INSTALLED_APP

설치가 완료되면 Django 프로젝트 settings.py의 INSTALLED_APP에 추가해준다.

서버별로 환경설정을 분리한 경우에는 알맞게 추가해준다.(settings/base.py)

 INSTALLED_APPS = [
     ...
    # django third-party-apps
    'sslserver',
    ...
]

runsslserver

$ python manage.py runsslserver --certificate {{certname}}.cert --key {{keyname}}.key
