Objective

Openssl
  • A P7B file is a text file that contains certificates and chain certificates, but does not contain the private key. PFX (PKCS#12) A PFX file is a binary format file for storing the server certificate, any intermediate certificates, and the private key in one encrypt-able file. Convert P7B to PFX.
  • Openssl pkcs7 -in test.p7b -printcerts -out test.pem openssl pkcs12 -export -in test.pem -inkey test.key -out test.p12 -name test.domain.net Check the created PKCS12 key store.

This article explains/guides how we can convert PKCS# certificates into a PEM format

Convert P7b To Crt Openssl

I have received a certificate in.p7b format. First, I converted it into.pem format. Then, I imported it into Firefox (or your browser). After that, I could access my application using that certificate. Now, in order to convert a.p7b into.pem do as follows. Openssl pkcs7 -inform der -in yourCert.p7b -printcerts -out yourCert.pem Hope this. This article will show you how to combine a private key with a.p7b certificate file to create a.pfx file on Windows Internet Information Server (IIS). These instructions presume that you have already used “Create Certificate Request” from within IIS to generate a private key and CSR on the server/laptop you are using.

Openssl P7b Extract Private Key

Instructions

  1. Copy the certificate to the appliance by using a secure copy utility, such as SCP.
  2. Convert the certificate (for example, cert.P7B ) to PEM format:
    > openssl pkcs7 -inform DER -in cert.p7b -print_certs -text -out cert.pem
Note: If the PKCS#7 cert is already in PEM format you will omit the -inform switch
  1. To make sure that the converted certificate is in correct x509 format, verify that the following command produces no error:
    [email protected]# openssl x509 -in cert.PEM -text
  2. Verify that the certificate file contains a private key. Begin by issuing the following command:
    [email protected]# cat cert.PEM
    Verify that the output file includes an RSA PRIVATE KEY section.
    -----BEGIN RSA PRIVATE KEY-----
    Mkm^s9KMs9023pz/s...
    -----END RSA PRIVATE KEY-----

    The following is another example of an RSA PRIVATE KEY section:
    Bag Attributes
    1.3.6.1.4.1.311.17.2: <No Values>
    localKeyID: 01 00 00 00

    5eU6ky3WYZ1BTy6thxxLlwAullynVXZEflNLxq1oX+ZYl6djgjE3qg
    -----END RSA PRIVATE KEY-----

    The following is a SERVER CERTIFICATE section:
    Bag Attributes
    localKeyID: 01 00 00 00
    friendlyName: AG Certificate
    subject=/C=AU/ST=NSW/L=Wanniassa/O=Dave Mother
    Asiapacific/OU=Support/CN=davemother.food.lan
    issuer=/DC=lan/DC=food/CN=hotdog
    -----BEGIN CERTIFICATE-----
    MIIFiTCCBHGgAwIBAgIKCGryDgAAAAAAHzANBgkqhkiG9w0BAQUFADA8MRMwEQYK
    ... (more random characters) 5pLDWYVHhLkA1pSxvFjNJHRSIydWHc5ltGyKqIUcBezVaXyel94pNSUYx07NpPV/
    MY2ovQyQZM8gGe3+lGFum0VHbv/y/gB9HhFesog=
    -----END CERTIFICATE-----

    The following is an INTERMEDIATE CA CERTIFICATE section:
    Bag Attributes: <Empty Attributes>
    subject=/DC=lan/DC=food/CN=hotdog
    issuer=/DC=lan/DC=food/CN=hotdog
    -----BEGIN CERTIFICATE-----
    MIIESDCCAzCgAwIBAgIQah20fCRYTY9LRXYMIRaKGjANBgkqhkiG9w0BAQUFADA8
    ... (more random characters) Nt0nksawDnbKo86rQcNnY5xUs7c7pj2zxj/IOsgNHUp5W6dDI9pQoqFFaDk=
    -----END CERTIFICATE-----

    Further Intermediate CA certificates may follow, depending on the certification path of the exported certificate.
  3. Open the .PEM file in a text editor
  4. Locate the first line of the .PEM file and the first instance of the following line, and copy those two lines and all the lines between them:
    -----END CERTIFICATE-----
    Note: Make sure that last copied line is the first -----END CERTIFICATE----- line in the .PEM file.
  5. Paste the copied lines into a new file. Call the new file something intuitive, such as cert-key.pem. This is the certificate-key pair for the server hosting the HTTPS service. This file should contain both the section labeled RSA PRIVATE KEY and the section labeled SERVER CERTIFICATE in the example above.
    Note: The certificate-key pair file contains the private key and must therefore be kept secure.
