What is keytool ?

Java Keytool is a key and certificate management utility. It allows users to manage their own public/private key pairs and certificates. It also allows users to cache certificates. Java Keytool stores the keys and certificates in what is called a keystore. By default the Java keystore is implemented as a file. It protects private keys with a password. A Keytool keystore contains the private key and any certificates necessary to complete a chain of trust and establish the trustworthiness of the primary certificate.
Each certificate in a Java keystore is associated with a unique alias. When creating a Java keystore you will first create the .jks file that will initially only contain the private key. You will then generate a CSR and have a certificate generated from it. Then you will import the certificate to the keystore including any root certificates. Java Keytool also several other functions that allow you to view the details of a certificate or list the certificates contained in a keystore or export a certificate.
Note: For easier management of your Java Keystores (using a GUI) check out Portecle. If you need to buy a certificate, try to compare SSL with our SSL Wizard.
