Windows + XAMPP + OpenSSL

Windows + XAMPP + OpenSSL

Posted at May 20,2011 2:34 AM
Tag:[Apache, OpenSSL, XAMPP]

ローカルPCでSSLを利用できるようにする実験です。環境はWindows Vista + XAMPP + OpenSSLで、XAMPPにバンドルされているopensslを利用します。XAMPPのバージョンは1.6.6aです。

この記事では証明書発行を自己署名で行っているため、「https://localhost~」でアクセスすると警告が表示されますが、有効期限が更新されることは確認できます。

4.sslフォルダ作成

C:¥xampp¥apache¥confにsslフォルダを作成します。

5.openssl起動

C:¥xampp¥apache¥conf¥sslに移動して、opensslを起動します。起動すると「OpenSSL>」というプロンプトが表示されます。

C:¥xampp¥apache¥conf¥ssl>C:¥xampp¥apache¥bin¥openssl
OpenSSL>

6.RSA 秘密鍵生成

OpenSSL> genrsa -out server.key 1024
Loading 'screen' into random state - done
Generating RSA private key, 1024 bit long modulus
.....................++++++
.++++++
e is 65537 (0x10001)

これでC:¥xampp¥apache¥conf¥ssl¥server.keyが生成されます。

7.CSR 生成

OpenSSL> req -new -config C:\xampp\apache\openssl\openssl.cnf -key server.key -o
ut csr.pem -sha1
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]:JP(国コード)
State or Province Name (full name) [Some-State]:Chiba(都道府県名)
Locality Name (eg, city) []:Ichikawa(市区町村名)
Organization Name (eg, company) [Internet Widgits Pty Ltd]:Apache Friends(組織名)
Organizational Unit Name (eg, section) []:XAMPP for Windows(組織内ユニット名)
Common Name (eg, YOUR name) []:localhost(アクセス名[http://アクセス名])
Email Address []:(管理者メールアドレス:オプション)
 
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:(Enter)
An optional company name []:(Enter)

これでC:¥xampp¥apache¥conf¥ssl¥csr.pemが生成されます。

8.証明書の発行

OpenSSL> x509 -in csr.pem -out server.crt -req -signkey server.key -days 365 -sh
a1
Loading 'screen' into random state - done
Signature ok
subject=/C=JP/ST=Chiba/L=Ichikawa/O=Apache Friends/OU=XAMPP for Windows/CN=local
host

これでC:¥xampp¥apache¥conf¥ssl¥server.crtが生成されます。

以降で使用するファイルはserver.keyとserver.crtのみです。

9.httpd-ssl.confの修正

C:¥xampp¥apache¥conf¥extra¥httpd-ssl.confの以下の赤色部分を修正します。

変更前

    #   Server Certificate:
    #   Point SSLCertificateFile at a PEM encoded certificate.  If
    #   the certificate is encrypted, then you will be prompted for a
    #   pass phrase.  Note that a kill -HUP will prompt again.  Keep
    #   in mind that if you have both an RSA and a DSA certificate you
    #   can configure both in parallel (to also allow the use of DSA
    #   ciphers, etc.)
    #SSLCertificateFile conf/ssl.crt/snakeoil-rsa.crt
    #SSLCertificateFile conf/ssl.crt/snakeoil-dsa.crt
    SSLCertificateFile conf/ssl.crt/server.crt
 
    #   Server Private Key:
    #   If the key is not combined with the certificate, use this
    #   directive to point at the key file.  Keep in mind that if
    #   you've both a RSA and a DSA private key you can configure
    #   both in parallel (to also allow the use of DSA ciphers, etc.)
    #SSLCertificateKeyFile conf/ssl.key/snakeoil-rsa.key
    #SSLCertificateKeyFile conf/ssl.key/snakeoil-dsa.key
    SSLCertificateKeyFile conf/ssl.key/server.key

変更後

    #   Server Certificate:
    #   Point SSLCertificateFile at a PEM encoded certificate.  If
    #   the certificate is encrypted, then you will be prompted for a
    #   pass phrase.  Note that a kill -HUP will prompt again.  Keep
    #   in mind that if you have both an RSA and a DSA certificate you
    #   can configure both in parallel (to also allow the use of DSA
    #   ciphers, etc.)
    #SSLCertificateFile conf/ssl.crt/snakeoil-rsa.crt
    #SSLCertificateFile conf/ssl.crt/snakeoil-dsa.crt
    SSLCertificateFile conf/ssl/server.crt
 
    #   Server Private Key:
    #   If the key is not combined with the certificate, use this
    #   directive to point at the key file.  Keep in mind that if
    #   you've both a RSA and a DSA private key you can configure
    #   both in parallel (to also allow the use of DSA ciphers, etc.)
    #SSLCertificateKeyFile conf/ssl.key/snakeoil-rsa.key
    #SSLCertificateKeyFile conf/ssl.key/snakeoil-dsa.key
    SSLCertificateKeyFile conf/ssl/server.key

これでApacheを再起動すれば、作成した証明書が適用されます。
