How exactly would I generate a.key file and a.crt file from a.p12 file? Stack Exchange Network Stack Exchange network consists of 175 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. A certificate.crt and privateKey.key can be extracted from your Personal Information Exchange file (certificate.pfx) using OpenSSL. Follow this article to create a certificate.crt and privateKey.key files from a certificate.pfx file. I want to create with java apis a keystore 'PCKS12' from an existing crt file. Is it possible? If yes how to make that? 1/ openssl req -newkey rsa:2048 -nodes -keyout keyFile.key -x509 -days 3650 -out certFile.crt 2/ openssl pkcs12 -export -in certFile.crt -inkey keyFile.key -out tmp.p12 -name alias. Create a identity certificate keystore by running the following two lines as one command in keytool: java utils.ImportPrivateKey -keystore newidentitykeystore.jks -storepass YOURPASSWORD -storetype JKS -keypass YOURPASSWORD -alias server -certfile tempcertfile.crt -keyfile yourdomainname.key -keyfilepass PFXPASSWORD.

  • Create PKCS 12 file using your private key and CA signed certificate of it. You can use openssl command for this. Create JKS file using keytool command. Step 3 (Optional). Changing the password of private key file in keystore. More details from here as well. Step 4 (Optional).

Certificate files for Java, Oracle, or Keytool SSL Keystore Installations

This page shows you how to remove your certificates and private key from a .pfx file and merge them into a Java, Oracle, or Keytool SSL Keystore.

.pfx files are Windows certificate backup files that combine your SSL Certificate's public key and trust chain with the associated private key.

To convert your certificates to a format that is usable by a Java-based server, you need to extract the certificates and keys from the .pfx file using OpenSSL, and then import the certificates to keystore using keytool.

The following steps require keytool, OpenSSL, and a Weblogic-specific utility.

Converting Files Using Weblogic

  1. Export your certificates to a .pfx file on your Microsoft server.
  2. Run the following OpenSSL command to extract your certificates and key from the .pfx file:

    openssl pkcs12 -in yourfilename.pfx -out tempcertfile.crt -nodes

  3. You should now have a file called tempcertfile.crt. Open this file with a text editor (such as WordPad). You will see the private key listed first, followed by your certificate information. -----BEGIN RSA PRIVATE KEY-----
    (Block of Encrypted Text)
    -----END RSA PRIVATE KEY-----
  4. Cut and paste all of the private key, including the BEGIN and END tags to a new text file and save it as your_domain_name.key

    The certificates remaining in your tempcertfile.crt will be in the following order: Server Certificate, Root Certificate, and Intermediate Certificate. However, depending on your .pfx export there could be 2–4 certificates inside the file. As long as you exported the certificates correctly, whatever you have in this file are the certificates that you are supposed to have.

    Make sure the private key was removed (not just copied and pasted), then save the file as your_domain_name.pem.

  5. Log into your DigiCert Management Console. Click the order number and download the TrustedRoot.crt file.

    You can make sure that you chose the right file by verifying that your trusted root was issued to and by the same organization.

    Note: Because DigiCert frequently issues certificates cross-signed by multiple Certificate Authorities for enhanced compatibility, your root certificate information could be different than what is shown in the image below.


  6. Create a trust certificate keystore by running the following two lines as one command in keytool:
    keytool -import -trustcacerts -file TrustedRoot.crt -alias server
    -keystore new_trust_keystore.jks -storepass YOURPASSWORD

    Remember to replace YOURPASSWORD with your password.

  7. Create a identity certificate keystore by running the following two lines as one command in keytool:

    java utils.ImportPrivateKey -keystore new_identity_keystore.jks -storepass
    YOURPASSWORD -storetype JKS -keypass YOURPASSWORD -alias
    server -certfile tempcertfile.crt -keyfile your_domain_name.key
    -keyfilepass PFXPASSWORD

    Remember to replace YOURPASSWORD with your password. Also replace PFXPASSWORD with the password that you created when you created your .pfx file.

    You now have two files: new_trust_keystore.jks and new_identity_keystore.jks. These files are ready to use with your Java-based server.

Creating a KeyStore in JKS Format

This section explains how to create a KeyStore using theJKS format as the database format for both the private key, and theassociated certificate or certificate chain. By default, as specifiedin the java.security file, keytool usesJKS as the format of the key and certificate databases (KeyStore andTrustStores). A CA must sign the certificate signing request (CSR).The CA is therefore trusted by the server-side application to whichthe Adapter is connected.

Note –

Itis recommended to use the default KeyStore


where <c:JavaCAPS> isthe directory where Java CAPS is installed and <MyDomain> isthe name of your domain.

To Generate a KeyStore

Generate Crt And Key From Jks Work

  1. Perform the following command.

    However, it's not compatible with Java. Do note that OpenSSL can also be used to create a similar container, namely PKCS12 (.p12). Key generate keygen vs openssl. This is a password protected container containing keys and certificates (just like Java's keystore).


  2. Once prompted, enter the information required to generatea CSR. A sample key generation section follows.


    If the KeyStore password is specified, then the password mustbe provided for the adapter.

  3. Press RETURN when prompted for the key password (thisaction makes the key password the same as the KeyStore password).

    This operation creates a KeyStore file clientkeystore in the current working directory. You must specify a fullyqualified domain for the “first and last name” question.The reason for this use is that some CAs such as VeriSign expect thisproperties to be a fully qualified domain name.

    Thereare CAs that do not require the fully qualified domain, but it isrecommended to use the fully qualified domain name for the sake ofportability. All the other information given must be valid. If theinformation cannot be validated, a CA such as VeriSign does not signa generated CSR for this entry.

    This KeyStore containsan entry with an alias of client.This entry consists of the generated private key and information neededfor generating a CSR as follows:


    This command generates a certificate signing request which canbe provided to a CA for a certificate request. The file client.csr contains the CSR in PEM format.

    Some CA (one trusted by the web server to which the adapteris connecting) must sign the CSR. The CA generates a certificate forthe corresponding CSR and signs the certificate with its private key.For more information, visit the following web sites:

    or

    If the certificate is chained with the CA’scertificate, perform step 4; otherwise, perform step 5 in the followinglist:

  4. Perform the following command.


    The command imports the certificate and assumes the client certificateis in the file client.cer and theCA’s certificate is in the file CARoot.cer.

  5. Perform the following command to import the CA’scertificate into the KeyStore for chaining with the client’scertificate.


  6. Perform the following command to import the client’scertificate signed by the CA whose certificate was imported in thepreceding step.


    The generated file clientkeystore containsthe client’s private key and the associated certificate chainused for client authentication and signing. The KeyStore and/or clientkeystore, can then be used as the adapter’sKeyStore.
