Generate a CSR: Apache (Open SSL)

To generate a Key Pair and Certificate Signing Request (CSR), please do the following:

PART 1: Generating the Key Pair

  • Step 1 of 4

    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.

  • Step 2 of 4

    Type the following command at the prompt:

    openssl genrsa -des3 -out 2048

    Please 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.

  • Step 3 of 4

    Enter the PEM Pass Phrase. (This MUST be remembered).

  • Step 4 of 4

    This will generate a 2048 RSA Private Key and store it in the file

PART 2: Generating the CSR

  • Step 1 of 4

    Type the following command at the prompt:

    openssl req -new -key -out

    Please note:You will be prompted for the PEM Pass Phrase if you included the -des3 command. Type it in now.

    Please note: There is a known issue with Apache/OpenSSL Windows Based Installations. If you receive an error with the above command, Please enter the following:

    openssl req -new -key -out -config openssl.cnf

  • Step 2 of 4

    Input the information for the Certificate Signing Request. This information will be displayed in the certificate.

    Please note:The following characters cannot 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) [GX Networks Ltd]:Webfusion
    • Organizational Unit Name (eg, section) []:IT
    • Common Name (eg, YOUR name) [] (Must be the FQDN – Fully Qualifed Domain Name)

    Important: DO NOT Enter the following:

    • Email Address []:
    • A challenge password []:
    • An optional company name []:
  • Step 3 of 4

    Please verify the CSR, to ensure all information is correct. Use the following command:

    openssl req -noout -text -in

  • Step 4 of 4

    The CSR will now be created.
