Certificate chains can be used to securely connect to the Oracle NoSQL Database Proxy. This section provides the steps to generate certificate chains and other required files for a secure connection using OpenSSL.
A certificate chain is provided by a Certificate Authority (CA). There are many CAs. Each CA has a different registration process to generate a certificate chain. Follow the steps provided by your CA for the process to obtain a certificate chain from them.
As a pre-requisite, download and install OpenSSL on the host machine. See OpenSSL .

Cisco asav download trial. To generate a certificate chain and private key using the OpenSSL, complete the following steps:
- On the configuration host, navigate to the directory where the certificate file is required to be placed.
- Create a 2048 bit server private key.The following output is displayed.
- This step is required only when your server private key is not in PKCS#8 format. Convert the private key to PKCS#8 format. When prompted, provide a secure password of your choice for the encryption.The following output is displayed.
- Create a Certificate Signing Request (CSR).where,
CN
in thesubj
should map the proxy domain name. - Send Certificate Signing Request (CSR) data file to CA. CA will use CSR data to issue a SSL certificate.
- CA returns a signed certificate
certificate.pem
. If it is not yet chained up with CA's certificate (rootCA.crt
), you need to manually chain up.
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 Linked Documentation. A.pfx file is a PKCS#12 archive: a file that can contain a lot of objects with optional password protection; but, usually, a PKCS#12 archive has a certificate (possibly with its assorted set of CA certificates) attached to it and the corresponding private key. Thats how.crt or.cer files differ from.pfx files - they contain a single.
key.pem
is the server private key.key-pkcs8.pem
is the server private key in PKCS#8 format.certificate.pem
is the certificate chain file in pem format. It includes the server certificate issued by CA and CA intermediate or root certificate.request.csr
is the server certificate request file.rootCA.crt
is the root certificate provided by the CA.
Additionally, a
driver.trust
file is also required if you are using the Java driver, and if the rootCA.crt
is not listed in Java default trust store JAVA_HOME/jre/lib/security/cacerts
. This driver.trust
file is not required for other language drivers. To generate the driver.trust
file, import the rootCA.crt
certificate to the Java keystore. When prompted, provide the keystore password. Generate Chain From Crt Key Files Free
For the Python driver, if your selected CA is not trusted by default, you need to get the
rootCA.crt
from CA and set the system environment variable: Generate Chain From Crt Key Files Online
How do I make my own bundle file from CRT files?
Answer: You may do this using you favorite text editor or by using the command line.
Example:
# Root CA Certificate - AddTrustExternalCARoot.crt
# Intermediate CA Certificate 1 - ComodoRSAAddTrustCA.crt OR ComodoECCAddTrustCA.crt
# Intermediate CA Certificate 2 - ComodoRSADomain/Organization/ExtendedvalidationSecureServerCA.crt OR ComodoRSAECCDomain/Organization/ExtendedvalidationSecureServerCA.crt
# Intermediate CA Certificate 3 - ComodoSHA256SecureServerCA.crt
# Your SSL Certificate - yourDomain.crt
Note: You will not need your SSL certificate for this exercise.
GUI Text Editor
1. Open All files in a text editor. (Remember, not your domain certificate.)
2. Create a new blank text file.
3. Copy contents of all files in reverse order and paste them into the new file.
Example: Intermediate 3, Intermediate 2, Intermediate 1, Root Certificate.
4. Save newly created file as 'yourDomain.ca-bundle'.
Command Line
Linux or UNIX-like Operating Systems:
-- cat ComodoRSAAddTrustCA.crt ComodoRSADomain/Organization/ExtendedvalidationSecureServerCA.crt AddTrustExternalCARoot.crt > yourDomain.ca-bundle
Answer: You may do this using you favorite text editor or by using the command line.
Example:
# Root CA Certificate - AddTrustExternalCARoot.crt
# Intermediate CA Certificate 1 - ComodoRSAAddTrustCA.crt OR ComodoECCAddTrustCA.crt
# Intermediate CA Certificate 2 - ComodoRSADomain/Organization/ExtendedvalidationSecureServerCA.crt OR ComodoRSAECCDomain/Organization/ExtendedvalidationSecureServerCA.crt
# Intermediate CA Certificate 3 - ComodoSHA256SecureServerCA.crt
# Your SSL Certificate - yourDomain.crt
