The code snippet below show you how to use the JDK Security API to generate public and private keys. A private key can be use to sign a document and the public key is use to verify that the signature of the document is valid.

In order to create a pair of private and public keys, select key type as RSA (SSH1/SSH2), specify key size, and click on Generate button. While the key generation process goes on, you can move mouse over blank area to generate randomness. As the keys are generated, the public key is displayed on the interface with key fingerprint and key comment. Nov 01, 2019 Choose a public and private key generator. The domain and selector are the input data used to generate a key pair, which consists of the public and the private key. The public key is used in the DNS TXT record, whereas the private key is used for the sending MTA. Check our blog post, “What is an MTA?”, if you need to brush up on what that is.

The private key is usually not generated first. In general, they're generated at the same time. For some schemes, the public key can be derived from the private key, but this doesn't always hold, and that will depend on specific properties of the particular public-key scheme.
The API we use to generate the key pairs is in the
java.security
package. That’s mean we have to import this package into our code. The class for generating the key pairs is KeyPairGenerator
. To get an instance of this class we have to call the getInstance()
methods by providing two parameters. The first parameter is algorithm and the second parameter is the provider.![Public key dan private key generator 2018 Public key dan private key generator 2018](/uploads/1/2/6/0/126094197/528932626.png)
After obtaining an instance of the key generator we have to initialize it. The
initialize()
method takes two parameters, the key size and a source of randomness. We set the key size to 1024
and pass and instance of SecureRandom
.Finally to generate the key pairs we call the
generateKeyPair()
method of the KeyPairGenerator
class. This will return a KeyPair
object from where we can get the PrivateKey
and PublicKey
by calling the getPrivate()
and getPublic()
method.Let’s see the code snippet below:
