How to convert a PFX certificate to a separate .key\/.crt file so it can be used in an Synology Diskstation<\/strong><\/p>\n

Install the required programs:<\/p>\n

    \n
  1. Download one of the win32 light OpenSSL: https:\/\/slproweb.com\/products\/Win32OpenSSL.html<\/a><\/li>\n
  2. Install it.<\/li>\n
  3. Make sure \u201dVisual C++ 2008 Redistributables\u201d is installed.<\/li>\n<\/ol>\n

    This version of OpenSSL requires a “openssl.cnf” configuration file:<\/p>\n

      \n
    1. Download http:\/\/www.tbs-certificats.com\/openssl-dem-server-cert-thvs.cnf<\/a> and rename it to \u201copenssl.cnf\u201d and save it in C:\\OpenSSL-Win32\\<\/li>\n
    2. Start a CMD, \u00a0go to c:\\OpenSSL-Win32\\bin\u00a0and enter: \u201cset OPENSSL_CONF=c:\\OpenSSL-Win32\\openssl.cnf\u201d<\/li>\n<\/ol>\n

      Convert the file:<\/p>\n

        \n
      1. Copy the .pxf certificate file to c:\\OpenSSL-Win32\\bin<\/li>\n
      2. In CMD go to c:\\OpenSSL-Win32\\bin<\/li>\n
      3. Type: openssl pkcs12 -in certname.pfx\u00a0\u2013nodes<\/em> -nocerts -out key.key<\/li>\n
      4. Type: openssl pkcs12 -in certname.pfx<\/em> -nokeys -out certificate.crt<\/li>\n<\/ol>\n

        Clean the files:<\/p>\n

          \n
        1. Open key.key in Wordpad or Notepad++ (NOT Notepad)<\/li>\n
        2. Remove everything before —–BEGIN CERTIFICATE—– and everything after —–END CERTIFICATE—–<\/li>\n
        3. Do the same for certificate.crt<\/li>\n<\/ol>\n

          You can now import the two files in your\u00a0Synology Diskstation<\/p>\n","protected":false},"excerpt":{"rendered":"
