To generate a Certificate Signing Request (CSR) for Apache HTTP Server, perform the following steps. They will enable you to get the CSR to complete the order process !
Note: to generate an ECC CSR, please follow this tutorial.
Step 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 in OpenSSL:
genrsa –des3 –out www.mydomain.com.key 2048 - Enter the PEM Pass Phrase (This MUST be remembered)
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.
Important Information: for all Windows OpenSSL users, please remove the -des3 parameter when generating the key. This will prevent any installation errors however will leave the private key unprotected.
Step 2: Generating the CSR
- Type the following command at the prompt in OpenSSL:
req –new –key www.mydomain.com.key –out www.mydomain.com.csr - Input the information for the Certificate Signing Request. This information will be displayed in the certificate.
- Common Name – Must match the URL you plan to secure exactly – is usually your fully-qualified domain name (e.g. devel.ssl247.co.uk or mail.devel.ssl247.co.uk). Remember the www. Is important – include it if you want to secure https://www.yoursite.com & exclude it if you want to secure https://yoursite.com.
- Organisation - The legal (officially registered) name of your organization/company include Inc., LLP., Pvt, Plc. Ltd. SARL., etc.
- Organisational unit - The name of your department within the organization (this is often "IT," "Web," or is just left blank).
- City/locality - The city or town in which your organization is located.
- State/province - The state in which your organization is located.
- Country - Click here for the official list of ISO country codes for this field.
- Please verify the CSR, to insure all information is correct. Use the following command:
req -noout -text -in www.mydomain.com.csr
Note 1: You will be prompted for the PEM Pass Phrase if you included the "-des3" command. Type it in now.
Note 2: There is a known issue with Apache/OpenSSL Windows Based Installations. If you recieve an error with the above command, Please enter the following:
req -new -key www.mydomain.com.key -out www.mydomain.com.csr -config openssl.cnf
Note: DO NOT Enter the following: "Email Address"; "A challenge password" & "An optional company name".
The CSR will now be created, and can be submitted via the website
You are now ready to submit your CSR for the certificate you wish to install.
