When you are working with JAVA applications and JAVA based server, you may need to configure a Java key store (JKS) file. Self signed keystore can be easily created with keytool command. But if you have a private key and a CA signedcertificate of it, You can not create a key store with just one keytool command.
You need to go through following to get it done.
Step 1. Create PKCS 12 file using your private key and CA signed certificate of it. You can use openssl command for this.
You can print the cert to pem format, then use openssl to print public key from the pem format. Add -rfc option to -printcert. Keytool -printcert -rfc -file client.crt. Save the output like below to a file client.pem. Apr 23, 2012 To create a private/public key with the alias specified by the user, enter: keytool -genkey -keyalg RSA -alias -keystore keystore.jks -storepass -keypass is the user-chosen alias for the private and public keys that will function as a user name for logging in using RSA. From my understanding it's impossible to do this with keytool alone. I use openssl for preparation. Suppose the key is in file key and the certificate is in a file cert.You have to create a PKCS12 file that contains both (because keytool can handle PKCS12 and JKS and I don't know if anything else). Puttygen (PuTTY Key Generator) WinSCP; Steps to perform: Open PuTTY Key Generator. Load your private key (.ppk file). Copy your public key data from the 'Public key for pasting into OpenSSH authorizedkeys file' section of the PuTTY Key Generator and paste the key data to the 'authorizedkeys' file (using notepad) if you want to use it.
If your private key has a password, It would promote to enter the password of private key. You need to define a password for PKCS 12 file as well.
As an example, say i have a private key called “server.pem” and certificate with “servercret.pem”
Step 2. Create JKS file using keytool command
Created PKCS 12 file has been given as the source keystore and new file name (wso2carbon.jks) has been given as the destination keystore.
As an example,
As an additional steps, you can change the private key password of the created JKS file and also the alias name for your private key entry.
Step 3 (Optional). Changing the password of private key file in keystore. More details from here as well
Step 4 (Optional). Change the alias name of the private key entry
By default [current alias] is set to “1”

You can verify keystore contents using this command:
3. Generate the Certificate Signing Request (CSR) using this command:
Submit contents of csr-for-myserver.pem file to your CA for signing
You can get a trial certificate from Thawte at https://www.thawte.com/cgi/server/try.exe
4. Save the signed certificate from CA to a file signed-cert.pem

You do this:
1. You convert the private key into PKCS#8 format:
2. Since the stupid Java keytool doesn't allow you to import private keys, you download this tool:

3. Now you can import the key into the Java Keystore:
4. Now you have the Java Keystore:
