Fedora18 証明書の作成

Fedora18 証明書の作成

●証明書の作成方法
[root@localhost ~]# cd /etc/pki/tls/certs/

サーバー鍵の作成

[root@localhost certs]# make server.key
umask 77 ; \
/usr/bin/openssl genrsa -aes128 2048 > server.key
Generating RSA private key, 2048 bit long modulus
........................................................................................+++
.............................+++
e is 65537 (0x10001)
Enter pass phrase: #パスフレーズ入力 0987654321 (例)
Verifying - Enter pass phrase:　　　　#再度入力

秘密鍵からパスフレーズを削除します

[root@localhost certs]# openssl rsa -in server.key -out server.key
Enter pass phrase for server.key:　　　　先ほどのパスフレーズを入力します
writing RSA key

証明書作成
[root@localhost certs]# make server.csr
umask 77 ; \
/usr/bin/openssl req -utf8 -new -key server.key -out server.csr
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.
-----　　　　　　　　　　　　　　　　　　↓以下任意に環境に合わせて入力ください
Country Name (2 letter code) [XX]:JP
State or Province Name (full name) []:Tokyo
Locality Name (eg, city) [Default City]:Tokyo
Organization Name (eg, company) [Default Company Ltd]:sample.com
Organizational Unit Name (eg, section) []:Web Server
Common Name (eg, your name or your server's hostname) []:sample.com
Email Address []:[e-mail]

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:0987654321
An optional company name []:

●有効期限が１０年の自己証明書を作成します。
[root@localhost certs]# openssl x509 -in server.csr -out server.crt -req -signkey server.key -days 3650
Signature ok
subject=/C=JP/ST=Tokyo/L=Tokyo/O=sample.com/OU=Web/CN=sample.com/emailAddress=[e-mail]
Getting Private key

証明書はroot以外読取できないようにします。
[root@localhost certs]# chmod 400 server.*
[root@localhost certs]# ls -l
