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.

Java KeyTool Step by Step Tutorial: Generate JKS KeyStore Using KeyTool and Export Certificate from KeyStore Java Keytool is a command line utility which can be used to generate keystores and then we can export keys and self signed public certificates from it with different command options provided by Java Key. To generate keystores: keytool -genkey -alias server -keyalg RSA -keystore server.jks keytool -genkey -alias client -keyalg RSA -keystore client.jks Getting server's self signed public key certificate and storing it in client's keystore and getting and storing client's self signed public key certificate in server's keystore. We will be able to see the entered values reflected on the private key entries on the keystore.jks file. Keytool -list -v -keystore keystore.jks Generate a CSR (Certificate Signing Request) From. May 08, 2011 The process could take a few days so I decided to just do some Googling on how to extract the keys/certificates from the keystore and convert it to PEM which Apache web server will accept. There doesn’t seem to be a quick way to directly convert from JKS to PEM so I had to convert from JKS to PKCS#12 first, then to PEM.

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.

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

Generate Jks File From Certificate

By default [current alias] is set to “1”

First, create the key pair: sn -k keypair.snk Next, extract the public key from the key pair and copy it to a separate file: sn -p keypair.snk public.snk Once you create the key pair, you must put the file where the strong name signing tools can find it. When signing an assembly with a strong name, the Assembly Linker (Al.exe) looks for the key file relative to the current directory and to the. Generate an RSA SSH keypair with a 4096 bit private key. Ssh-keygen -t rsa -b 4096 -C 'RSA 4096 bit Keys'. Generate an DSA SSH keypair with a 2048 bit private key. Ssh-keygen -t dsa -b 1024 -C 'DSA 1024 bit Keys'. Generate an ECDSA SSH keypair with a 521 bit private key. How to generate private key. Generate online private and public key for ssh, putty, github, bitbucket. Save both of keys on your computer (text file, dropbox, evernote etc)! The generated keys are random/unique and we can't restore a missing key. You will need to copy/set the public key on to the remote server/service. It then occurred to me (and a head slapped followed), that I have fairly recently published a library for Javascript RSA encryption which includes private and public key generation for RSA encryption. Not only that, but this is all available online.

The public and private keys are known as a keypair. You can specify an existingkey pairor a new key pair that you create at launch. Generate auth secret key in terminal. Public key cryptography enables you to securely access your instancesusing a private key instead of a password.When you launch an instance, you specify the key pair. At boot time, the public keycontent is placed on the instance in an entry within/.ssh/authorizedkeys.
