รุ่นแก้ไขเมื่อ 16:37, 20 พฤษภาคม 2564 โดย It (คุย | มีส่วนร่วม)
1. สร้าง private key
# cd /etc/pki/tls/certs # make eai.key
umask 77 ; \ /usr/bin/openssl genrsa -aes128 2048 > eai.key Generating RSA private key, 2048 bit long modulus ... ... e is 65537 (0x10001) Enter pass phrase: #set passphrase Verifying - Enter pass phrase: #confirm
2. ถอด Passphase ออกจาก private key ที่สร้างขึ้น
# openssl rsa -in eai.key' -out eai.key
Enter pass phrase for eai.key: #input passphrase writing RSA key
3. สร้าง csr
# make eai.csr
umask 77 ; \ /usr/bin/openssl req -utf8 -new -key eai.key -out eai.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. ----- Country Name (2 letter code) [XX]:TH #country State or Province Name (full name) []:Bangkok #state Locality Name (eg, city) [Default City]:Dusit #city Organization Name (eg, company) [Default Company Ltd]:EAI #company Organizational Unit Name (eg, section) []:IT #department Common Name (eg, your name or your server's hostname) []:mail.eai.in.th #server's FQDN Email Address []:xxx@eai.in.th #email address Please enter the following 'extra' attributes to be sent with your certificate request A challenge password []: #Enter An optional company name []: #Enter
4. ทำการ generate key
# openssl x509 -in eai.csr -out eai.crt -req -signkey eai.key -days 3650
