To Generate a Certificate by Using keytool
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. Jul 09, 2019 The private key gets generated along with your Certificate Signing Request (CSR). The CSR is submitted to the certificate authority right after you activate your certificate, while the private key must be kept safe and secret on your server or device. Later on, this key is used for installation of your certificate. Jul 09, 2019 If the Private Key key file is lost, you’ll need to reissue your Certificate. Can I generate a new Private Key for my Certificate if I lose the old one? You can generate a new private key and CSR, or use the automatic CSR and key generation during Certificate reissue (this option is available for all Certificates except for the Multi.
By default, the keytool utility creates a keystorefile in the directory where the utility is run.
Before You Begin
To run the keytool utility, your shell environmentmust be configured so that the J2SE /bin directory is inthe path, otherwise the full path to the utility must be present on the commandline.

Change to the directory that contains the keystore and truststorefiles.
Always generate the certificate in the directory containingthe keystore and truststore files. The default is domain-dir/config.
Generate the certificate in the keystore file, keystore.jks,using the following command format:
Use any unique name as your keyAlias. Ifyou have changed the keystore or private key password from the default (changeit), substitute the new password for changeit.The default key password alias is s1as.
A prompt appears that asks for your name, organization, and other information.
Export the generated certificate to the server.cer file(or client.cer if you prefer), using the following commandformat:
If a certificate signed by a certificate authority is required,see To Sign a Certificate by Using keytool.
Create the cacerts.jks truststore file andadd the certificate to the truststore, using the following command format:
If you have changed the keystore or private key password from the default(changeit), substitute the new password.
Information about the certificate is displayed and a prompt appearsasking if you want to trust the certificate.
Type yes, then press Enter.

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