Generate Pem From Csr And Key

inocfesricigau 2020. 11. 26. 11:37


  1. See Example: SSL Certificate - Generate a Key and CSR. Tableau Server uses Apache, which includes OpenSSL. You can use the OpenSSL toolkit to generate a key file and Certificate Signing Request (CSR) which can then be used to obtain a signed SSL certificate. Steps to generate a key and CSR.
  2. Alternatively, if you want to generate a PKCS12 from a certificate file (cer/pem), a certificate chain (generally pem or txt), and your private key, you need to use the following command: openssl pkcs12 -export -inkey yourprivatekey.key -in yourcertificate.cer -certfile yourchain.pem -out finalresult.pfx.

Openssl x509 -req -in mycsr.pem -forcepubkey mypubkey.pem -CA dumyCA.pem -CAkey -dumyCA.pem -out mycert.pem After this I take the outputted certificate and change its attributes to associate it with a private key. This all works nicely. The problem with this is that if I were to take the said csr, and submit it to a CA they would return to me.

.pem SSL Creation Instructions

SSL .pem files (concatenated certificate container files), are frequently required for certificate installations when multiple certificates are being imported as one file.

This article contains multiple sets of instructions that walk through various .pem file creation scenarios.

Creating a .pem with the Entire SSL Certificate Trust Chain

  1. Log into your DigiCert Management Console and download your Intermediate (DigiCertCA.crt), Root (TrustedRoot.crt), and Primary Certificates (your_domain_name.crt).
  2. Open a text editor (such as wordpad) and paste the entire body of each certificate into one text file in the following order:

    1. The Primary Certificate - your_domain_name.crt
    2. The Intermediate Certificate - DigiCertCA.crt
    3. The Root Certificate - TrustedRoot.crt

    Make sure to include the beginning and end tags on each certificate. The result should look like this:

    -----BEGIN CERTIFICATE-----
    (Your Primary SSL certificate: your_domain_name.crt)
    -----END CERTIFICATE-----

    -----BEGIN CERTIFICATE-----
    (Your Intermediate certificate: DigiCertCA.crt)
    -----END CERTIFICATE-----

    -----BEGIN CERTIFICATE-----
    (Your Root certificate: TrustedRoot.crt)
    -----END CERTIFICATE-----

    Save the combined file as your_domain_name.pem. The .pem file is now ready to use.

Creating a .pem with the Server and Intermediate Certificates

  1. Log into your DigiCert Management Console and download your Intermediate (DigiCertCA.crt) and Primary Certificates (your_domain_name.crt).
  2. Open a text editor (such as wordpad) and paste the entire body of each certificate into one text file in the following order:

    1. The Primary Certificate - your_domain_name.crt
    2. The Intermediate Certificate - DigiCertCA.crt

    Make sure to include the beginning and end tags on each certificate. The result should look like this:

    -----BEGIN CERTIFICATE-----
    (Your Primary SSL certificate: your_domain_name.crt)
    -----END CERTIFICATE-----

    -----BEGIN CERTIFICATE-----
    (Your Intermediate certificate: DigiCertCA.crt)
    -----END CERTIFICATE-----

    Save the combined file as your_domain_name.pem. The .pem file is now ready to use.

Creating a .pem with the Private Key and Entire Trust Chain

  1. Log into your DigiCert Management Console and download your Intermediate (DigiCertCA.crt) and Primary Certificates (your_domain_name.crt).
  2. Open a text editor (such as wordpad) and paste the entire body of each certificate into one text file in the following order:

    1. The Private Key - your_domain_name.key
    2. The Primary Certificate - your_domain_name.crt
    3. The Intermediate Certificate - DigiCertCA.crt
    4. The Root Certificate - TrustedRoot.crt

    Make sure to include the beginning and end tags on each certificate. The result should look like this:

    -----BEGIN RSA PRIVATE KEY-----
    (Your Private Key: your_domain_name.key)
    -----END RSA PRIVATE KEY-----

    -----BEGIN CERTIFICATE-----
    (Your Primary SSL certificate: your_domain_name.crt)
    -----END CERTIFICATE-----

    -----BEGIN CERTIFICATE-----
    (Your Intermediate certificate: DigiCertCA.crt)
    -----END CERTIFICATE-----

    -----BEGIN CERTIFICATE-----
    (Your Root certificate: TrustedRoot.crt)
    -----END CERTIFICATE-----

    Save the combined file as your_domain_name.pem. The .pem file is now ready to use.

You can also use Microsoft IIS to generate a Private Key and CSR.

How to generate a CSR in Microsoft IIS 7

1. Click Start, then Administrative Tools, then Internet Information Services (IIS) Manager.
2. Click on the server name.
3. From the center menu, double-click the 'Server Certificates' button in the 'Security' section (it is near the bottom of the menu).

4. Next, from the 'Actions' menu (on the right), click on 'Create Certificate Request.' This will open the Request Certificate wizard.

5. In the 'Distinguished Name Properties' window, enter the information as follows:

  1. Common Name - The name through which the certificate will be accessed (usually the fully-qualified domain name, e.g., www.domain.com or mail.domain.com).
  2. Organization - The legally registered name of your organization/company.
  3. Organizational unit - The name of your department within the organization (frequently this entry will be listed as 'IT,' 'Web Security,' or is simply left blank).
  4. City/locality - The city in which your organization is located.
  5. State/province - The state in which your organization is located.

6. Click Next.
7. In the 'Cryptographic Service Provider Properties' window, leave both settings at their defaults (Microsoft RSA SChannel and 2048) and then click next.

8. Enter a filename for your CSR file.

9. Remember the filename that you choose and the location to which you save it. You will need to open this file as a text file and copy the entire body of it (including the Begin and End Certificate Request tags) into the online order process when prompted

2. Back Up Private Key

To backup a private key on Microsoft IIS 6.0 follow these instructions:

1. From your server, go to Start > Run and enter mmc in the text box. Click on the OK button.
2. From the Microsoft Management Console (MMC) menu bar, select Console > Add/Remove Snap-in.
3. Click on the Add button. Select Certificates from the list of snap-ins and then click on the Add button.

4. Select the Computer account option. Click on the Next button.

5. Select the Local computer (the computer this console is running on) option. Click on the Finish button.
6. Click on the Close button on the snap-in list window. Click on the OK button on the Add/Remove Snap-in window.
7. Click on Certificates from the left pane. Look for a folder called REQUEST or 'Certificate Enrollment Request> Certificates

8. Select the private key that you wish to backup. Right click on the file and choose > All Tasks > Export

9. The certificate export wizard will start, please click Next to continue. In the next window select Yes, export the private key and click Next

10. Leave the default settings selected and click Next.

11. Set a password on the private key backup file and click Next
12. Click on Browse and select a location where you want to save the private key Backup file to and then click Next to continue. By default the file will be saved with a .pfx extension.
13. Click Finish, to complete the export process

3. Convert to RSA Private Key Format

The private key is backed up as a ‘.pfx’ file, which stands for Personal Information Exchange.

To convert it to RSA Private Key format supported by inSync:

Pem

1. Download and install latest version of OpenSSL for windows from http://www.slproweb.com/products/Win32OpenSSL.html.

Note: OpenSSL requires Visual C++ 2008 Redistributables which can be downloaded from the same website.

2. Open command prompt, navigate to C:OpenSSL-Win32bin>, and run the following commands.

3. The private key will be saved as ‘myserver.key’.

4. Carefully protect the private key. Be sure to backup the private key, as there is no means to recover it, should it be lost.
