How to Generate Certificate Signing Request on FileZilla using OpenSSL

Use these instructions to build your own shell commands to generate your FileZilla CSR.

If you prefer, you can build your own shell commands to generate your FileZilla CSR.

  1. Use your terminal (ssh) to login to your FileZilla server.
  2. At the prompt, enter the following command, making sure to replace server with the name of your server:openssl req –new –newkey rsa:2048 –nodes –keyoutserver.key –out server.csr
  3. This starts the process for generating two files:
    • The Private-Key file for the decryption of your SSL Certificate.
    • A Certificate Signing Request (CSR) file, used to apply for your SSL Certificate.
  4. When you are prompted for the Common Name (domain name), enter the fully qualified domain name (FQDN) for the site that you are securing.
  5. When you are prompted, enter your organizational information beginning with your geographic information.

    Note: You may have default information set already.

    This creates your OpenSSL .csr file.

  6. Open the .csr file with a text editor.
  7. Copy the content, including the BEGIN and END tags, and paste it into the Certificate order form.
  8. Save (back up) the generated .key file. You need it later for your SSL Certificate installation.
  9. After you receive your SSL Certificate, you can install it.
