PART 1: Generating the Key Pair
- The utility “OpenSSL” is used to generate both Private Key (key) and Certificate Signing request (CSR). OpenSSL is usually installed under /usr/local/ssl/bin. If you have a custom install, you will need to adjust these instructions appropriately.
- Type the following command at the prompt:
opensslgenrsa –des3 –out www.mydomain.com.key 2048
Note: If you do not wish to use a Pass Phrase, do not use the -des3 command. It will however leave the private key unprotected.
- Enter the PEM Pass Phrase (This MUST be remembered)
- This will generate a 2048 RSA Private key, and stores it in the file www.mydomain.com.key.
PART 2:Generating the CSR
- Type the following command at the prompt:
opensslreq –new –key www.mydomain.com.key –out www.mydomain.com.csr
Note: You will be prompted for the PEM Pass Phrase if you included the “-des3” command. Type it in now.
NOTE: There is a known issue with Apache/OpenSSL Windows Based Installations. If you recevie an error with the above command, Please enter the following:
openssl req -new -key www.mydomain.com.key -out www.mydomain.com.csr -config openssl.cnf
- Input the information for the Certificate Signing Request. This information will be displayed in the certificate.
Note: The following characters can not be accepted: < > ~ ! @ # $ % ^ * / ( ) ?.,&
- Country Name (2 letter code) [AU]:GB
- State or Province Name (full name) [Some-State]:London
- Locality Name (eg, city) []:London
- Organization Name (eg, company) [Internet Widgits Pty Ltd]:Global Sign
- Organizational Unit Name (eg, section) []:IT
- Common Name (eg, YOUR name) []:www.globalsign.net (Must be the FQDN – Fully Qualifed Domain Name)
Note: DO NOT Enter the following:
- Email Address []:
- A challenge password []:
- An optional company name []:
- Please verify the CSR, to insure all information is correct. Use the following command:
opensslreq -noout -text -in www.mydomain.com.csr
- The CSR will now be created, and can be submitted via the website.
