If you need to create an integration that consumes external REST APIs hosted on a two-way, SSL-enabled server, you must create the keystore file required for establishing an Oracle Integration identity to facilitate a two-way, SSL-based integration. Ensure that the server on which the external REST APIs are hosted is enabled for two-way SSL support. Use Java version 1.8 or higher.

Openssl Pem To Jks

Convert Pem To Jks Windows

Openssl x509 -inform der -in pathtoDERcertificate-out pathtoPEMcertificate Convert a.pfx file to a JKS store. To convert the PEM-format keys to Java KeyStores: Convert the certificate from PEM to PKCS12, using the following command: openssl pkcs12 -export -out eneCert.pkcs12 -in eneCert.pem. You may ignore the warning message this command issues. Enter and repeat the export password.

You can obtain the client certificate in a variety of ways. Select the method that is best for your environment. For example, you can obtain the certificate directly from many certificate authorities. The steps in this section describe how to generate a certificate signing request (CSR) and have it signed by a well known certificate authority.

Note:

Inbound (trigger-based) two-way SSL is not supported.

Commonly Used Terms and Tools

TermDescription
Secure socket layer (SSL) and Transport Layer Security (TLS)SSL and TLS, its successor, are protocols for establishing authenticated and encrypted links between networked computers.
Digital certificateA data file that holds the cryptographic key provided to an organization or entity by a trusted authority. A simple analogy is a driver's license. The license uniquely identifies the person to whom it is issued. The license is issued by the DMV, a trusted authority.
CertificateA public key and private key form a pair used to encrypt and decrypt data. Public keys can be freely given to anyone who needs to securely exchange data. Private keys must never be shared and must be stored securely. If private keys are listed or compromised, the issuing certificate authority must be notified so they can be added to the certificate revocation list.
Certificate authority (or certification authority)An entity that issues digital certificates. A digital certificate certifies the ownership of a public key by the named subject of the certificate.
Certificate encoding/formats
  • Privacy Enhanced Mail (PEM): The full specification of PEM is in RFC 7468. PEM is the most commonly-used X509 certificate format. It's a base64-encoded string enclosed between:-----BEGIN CERTIFICATE----- and -----END CERTIFICATE-----
  • Distinguished Encoding Rules (DER): Binary Format. Cannot be viewed in an editor.
  • Public Key Cryptography Standards (PKCS): These are a group of public key cryptography standards devised and published by RSA Security LLC. See https://datatracker.ietf.org/wg/pkix/documents/.
TrustStoreA password-protected repository for trust or public certificates. The default location in Java is $JAVA_HOME/jre/lib/security/cacerts. All well known certificate authority root and intermediate certificates are available in the JDK truststore.
KeystoreA password-protected repository to hold client or private certificates. Since this store holds private keys, it is imperative that the store resides in a secure location.
Certificate chainA certificate chain is an ordered list of certificates ending with the root certificate. For trust to be established, the entire certificate chain is traversed. Each certificate is validated by finding the public key of the next issuing certificate authority or intermediate certificate authority, until the root certificate is reached. Certificate chains are usually cached to validate the certificate locally.
The two most commonly used tools for SSL are the following:

To upload an identity certificate:

  1. In the navigation pane, select Home > Settings > Certificates.
  2. Click Upload.
  3. Set the alias name to the alias listed in the keystore for the identity certificate. (Use keytool -list to see the contents of the keystore.)
  4. Make sure the certificate category is set to Identity.
  5. Upload the client certificate file in JKS format.
  6. Enter the keystore and key passwords used to create the JKS store. If there is a mismatch in the passwords, Oracle Integration cannot access the identity certificates.
  7. Create a new adapter connection (SOAP Adapter or REST Adapter connection) in Oracle Integration.
  8. On the Connections page, select the two-way SSL checkbox and associate the alias required by the connection to use to complete the SSL connection. This alias must match the value that was entered in the Upload Certificate dialog.

To test Mutual TLS authentication (mTLS):

  1. Test access to the endpoint from the browser first. Import the client certificate in .p12 format into the browser of choice.
  2. Enter the endpoint in the browser bar and press Enter. A message is displayed asking you to use the client certificate that was imported.
  3. Follow the prompts in the message. If the certificate is valid, content is loaded in the browser.
  4. If the browser test was successful, test the REST/SOAP adapter connection in Oracle Integration.
