Pem Public Key

M keyformat Specify a key format for the -i (import) or -e (export) conversion options. The supported key formats are: ``RFC4716' (RFC 4716/SSH2 public or private key), ``PKCS8' (PEM PKCS8 public key) or ``PEM' (PEM public key). The default conversion format is ``RFC4716'. [email protected] secure openssl genrsa -out posvendor.key.pem 2048 [email protected] secure openssl rsa -in posvendor.key.pem -pubout -out posvendor.pub.pem writing RSA key [email protected] secure ls posvendor.key.pem posvendor.pub.pem. So we have public and private keys generated. For the same of example, here is the path of the pem files generated.

.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.

Pem Public Key

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.

How do I convert my Amazon Elastic Compute Cloud (Amazon EC2) Privacy Enhanced Mail (.pem) file to a PuTTY Private Key (.ppk) file? Or, convert a .ppk file to a .pem file?

Short description

PuTTY doesn't natively support the private key format (.pem) generated by Amazon EC2. You must convert your private key into a .ppk file before you can connect to your instance using PuTTY. You can use the PuTTYgen tool for this conversion.

Resolution

Windows - install PuTTYgen

Most Windows operating systems have PuTTY installed. If your system doesn't, download and install PuTTYgen.

Windows - convert a .pem file to a .ppk file

Start PuTTYgen, and then convert the .pem file to a .ppk file. For detailed steps, see Convert your private key using PuTTYgen.

Windows - convert a .ppk file to a .pem file

  1. Start PuTTYgen. For Actions, choose Load, and then navigate to your .ppk file.
  2. Choose the .ppk file, and then choose Open.
  3. (Optional) For Key passphrase, enter a passphrase. For Confirm passphrase, re-enter your passphrase.
    Note: Although a passphrase isn't required, you should specify one as a security measure to protect the private key from unauthorized use. Using a passphrase makes automation difficult, because human intervention is needed to log in to an instance or to copy files to an instance.
  4. From the menu at the top of the PuTTY Key Generator, choose Conversions, Export OpenSSH Key.
    Note: If you didn't enter a passphrase, you receive a PuTTYgen warning. Choose Yes.
  5. Name the file and add the .pem extension.
  6. Choose Save.

Unix or Linux - install PuTTY

Install PuTTY, if it's not already on your system.

Important: The Extra Packages for Enterprise Linux (EPEL) repository contains the PuTTY package. You must enable the EPEL repository before you install PuTTY.

To install PuTTY, run one of the following commands:

RPM-based

Dpkg-based

Unix or Linux - convert a .pem file to a .ppk file

On the instance shell, run the puttygen command to convert your .pem file to a .ppk file:
