Akka HTTPでHTTPS通信する

Posted at

Akka HTTPで(とりあえず)HTTPS通信をするための備忘録。

Akka HTTPでHTTPS通信をするには?

公式ドキュメントに書いてあるとおりにする。
言われたとおりにするためにPKCS12形式のファイルを作成する。

PKCS12ファイルの作成

秘密鍵の作成

# AES128で2048bitの秘密鍵
# このファイルは公開してはいけない
> openssl genrsa -aes128 2048 > sample.key

Generating RSA private key, 2048 bit long modulus
....+++
.........................+++
e is 65537 (0x010001)
Enter pass phrase:
Verifying - Enter pass phrase:

CSR(証明書署名要求)の作成

色々聞かれるけど、任意入力なので無視することも可能。

> openssl req -new -key sample.key > sample.csr

Enter pass phrase for sample.key:
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.

署名

# 有効期限は365000日(1000年)
> openssl x509 -in sample.csr -days 365000 -req -signkey sample.key > sample.crt

Signature ok
subject=C = AU, ST = Some-State, O = Internet Widgits Pty Ltd
Getting Private key
Enter pass phrase for sample.key:

PKCS12形式に変換する

> openssl pkcs12 -export -inkey sample.key -in sample.crt -out sample.p12

Enter pass phrase for sample.key:
Enter Export Password:

あとは

resourcesなどのパスが通っている場所にPKCS12ファイルを置けばAkka HTTPでHTTPS通信ができるようになる。
