Introduction

The generated file clientkeystore contains the client’s private key and the associated certificate chain used for client authentication and signing. The KeyStore and/or clientkeystore, can then be used as the adapter’s KeyStore. Creating a KeyStore in PKCS12 Format This section explains how to create a PKCS12 KeyStore to work with JSSE.

• The Java Keytool is a command line tool which can generate public key / private key pairs and store them in a Java KeyStore.The Keytool executable is distributed with the Java SDK (or JRE), so if you have an SDK installed you will also have the Keytool executable.
• Keytool commands The keytool command interface has changed in Java SE 6. See the Changes Section for a detailed description. Note that previously defined commands are still supported. DESCRIPTION keytool is a key and certificate management utility. It allows users to administer their own public/private key pairs and associated certificates.
• Dec 16, 2012  AES is a symmetric key algorithm; hence we prefer to generate a single secret key using the flag –genseckey. Further, the default Key store type is JKS for the Java keytool which cannot store symmetric keys. Hence the keystore type is changed to JCEKS for AES encryption algorithm. The commands to generate AES Keys in the Java Keystore are as.

This article covers the creation of a new Java keystore using Java keytool.

Process

You can watch the video below for a tutorial.

Or, you can check the step by step guidelines below.
1. Create a new keystore:
Open a command prompt in the same directory as Java keytool; alternatively, you may specify the full path of keytool in your command. Pay close attention to the alias you specify in this command as it will be needed later on.
keytool -genkey -alias mydomain -keyalg RSA -keystore KeyStore.jks -keysize 2048
2. Generate a CSR based on the new keystore:
keytool -certreq -alias mydomain -keystore KeyStore.jks -file mydomain.csr
Answer each question when prompted. Use the chart below to guide you through the process:

Confirm or reject the details by typing 'Yes' or 'No' and pressing Enter
Press EnterDon't starve together key generator. to use the same password as the keystore, alternatively specify a separate password and press enter.
You should now have a file called mydomain.csr which can be used to order or reissue a digital certificate from GlobalSign.
3. While the order processes, download the root & intermediate certificates for your order. You can identify the correct root & intermediate certificate based on hash algorithm and product type.
4. Import the root & intermediate certificates into your keystore. Import the root certificate first, followed by the intermediate. Make sure you specify the correct alias of 'root' and 'intermediate' respectively.
keytool -import -trustcacerts -alias root -file root.crt -keystore KeyStore.jks
keytool -import -trustcacerts -alias intermediate -file intermediate.crt -keystore KeyStore.jks
5. Download & import your new certificate
Download your new certificate; save it as mydomain.crt.
Use the same alias as the private key so it associates them together. The alias here must match the alias of the private key in the first command.
keytool -import -trustcacerts -alias mydomain -file mydomain.crt -keystore KeyStore.jks
The keystore is now complete and can be used for signing code or deploying on a Java based web server depending on the product you ordered.

If a code signer does not yet have a suitable private key for signing the code, the key must first be generated, along with a corresponding public key that can be used by the code receiver's runtime system to verify the signature.

Java Keystore Generate Aes Key

Since this lesson assumes that you don't yet have such keys, you are going to create a keystore named examplestore and create an entry with a newly generated public/private key pair (with the public key in a certificate).

Type the following command in your command window to create a keystore named examplestore and to generate keys:

You will be prompted to enter passwords for the key and keystore.

Subparts of the keytool Command

Let's look at what each of the keytool subparts mean.

• The command for generating keys is -genkey.
• The -alias signFiles subpart indicates the alias to be used in the future to refer to the keystore entry containing the keys that will be generated.
• The -keystore examplestore subpart indicates the name (and optionally path) of the keystore you are creating or already using.
• The storepass value that you are promted for specifies the keystore password.
• The keypass value that you are prompted for specifies a password for the private key about to be generated. You will always need this password in order to access the keystore entry containing that key. The entry doesn't have to have its own password. When you are prompted for the key password, you are given the option of letting it be the same as the keystore password.

Note: For security reasons you should not set your key or keystore passwords on the command line, because they can be intercepted more easily that way.

Distinguished-Name Information

If you use the preceding keystore command, you will be prompted for your distinguished-name information. Following are the prompts; the bold indicates what you should type.

Command Results

The keytool command creates the keystore named examplestore (if it doesn't already exist) in the same directory in which the command is executed. The command generates a public/private key pair for the entity whose distinguished name has a common name of Susan Jones and the organizational unit of Purchasing.

The command creates a self-signed certificate that includes the public key and the distinguished-name information. (The distinguished name you supply will be used as the 'subject' field in the certificate.) This certificate will be valid for 90 days, the default validity period if you don't specify a -validityNeed for speed 2015 pc key generator. option. The certificate is associated with the private key in a keystore entry referred to by the alias signFiles.

Self-signed certificates are useful for developing and testing an application. However, users are warned that the application is signed with an untrusted certificate and asked if they want to run the application. To provide users with more confidence to run your application, use a certificate issued by a recognized certificate authority.

Note: The command could be shorter if option defaults are accepted or you wish to be prompted for various values. Whenever you execute a keytool command, defaults are used for unspecified options that have default values, and you are prompted for any required values. For the genkey command, options with default values include alias (whose default is mykey), validity (90 days), and keystore (the file named .keystore in your home directory). Required values include dname, storepass, and keypass.
