Replacing Keys

  1. Use the private-key.pem and the digital-certificate.txt on your website in place of the old copies.
    • The private key is generally located in a non-public directory, used by a signing mechanism (2.0 | 1.9). This is generally referenced in a file named sign-message.php or similar.
    • The certificate is generally located in a public directory used by JavaScript on initial connection (2.0 | 1.9). If it doesn't work properly after being replaced, you can force a reload of the cache by modifying the URL. e.g. http://foo/bar/digital-certificate.txt?modify_url
    • The public key is not needed for signing and can be saved for next renewal time.
