3.3.1 Create Public and Private Key Pair

This topic provides the information on creating the public and private key pair using the command to obtain the identity store.

Browse to the bin folder of JRE from the command prompt and type the following command.

keytool -genkeypair -alias alias -keyalg keyalg -keysize keysize - sigalg sigalg -validity valDays -keystore keystore

Note:

The items highlighted are placeholders, and should be replaced with suitable values when running the command.

In the above command:

Table 3-2 Description of Placeholders

Placeholder	Description
alias	alias is used to identify the public and private key pair created. This alias is required later when configuring the SSL attributes for the managed servers in Oracle Weblogic Server.
keyalg	keyalg is the key algorithm used to generate the public and private key pair. The RSA key algorithm is recommended.
keysize	keysize is the size of the public and private key pairs generated. A key size of 1024 or more is recommended. Please consult with your CA on the key size support for different types of certificates.
sigalg	sigalg is the algorithm used to generate the signature. This algorithm should be compatible with the key algorithm and should be one of the values specified in the Java Cryptography API Specification and Reference.
valdays	valdays is the number of days for which the certificate is to be considered valid. Consult with your CA on this period.
keystore	keystore is used to specify the location of the JKS file. If no JKS file is present in the path provided, a JKS file will be created.

The command prompts for the following attributes of the certificate and keystore:

Table 3-3 Description of Attributes

Attribute	Description
Keystore Password	Specify a password that will be used to access the keystore. This password needs to be specified later when configuring the identity store in the Oracle Weblogic Server.
Key Password	Specify a password that will be used to access the private key stored in the keystore. This password needs to be specified later when configuring the SSL attributes of the managed server(s) in the Oracle Weblogic Server.
First and Last Name (CN)	Enter the domain name of the machine used to access Oracle Banking Origination, for instance, www.example.com
Name of your Organizational Unit	The name of the department or unit making the request, for example, BPD. Use this field to further identify the SSL Certificate you are creating, for example, by department or by the physical server.
