What is Java 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.

Generally Java folder is in C:/Program Files/then move inside that folder to jre6 or jre7. and then move to bin folder. To make things more clear i will post a image/screenshot of it.

• Go to this directory and then enter the following command

Now after you enter the above code you may get the following error

After you have downloaded the zip file. Just extract the file to you required path. Preferably (program files) for eg.

C:Program Filesopenssl

• After this, you need to tweak the previous command in the command prompt a bit.

If you have saved the `OpenSSL` folder in example path

• Then you will be asked for password
