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.
Extracting the Public Key from the Private Key as a SubjectPublicKeyInfo. PKCS#8 files are self-describing, and PKCS#8 private key files contain the public key, so the public key can be extracted from the private key file: openssl pkey -pubout -inform der -outform der -in -out. Can I generate a new private key for my SSL certificate? Since a public key with the additional information (i.e., domain name and administrative contact information) must be signed by a trusted certificate authority in order to make it applicable and legitimate for securing communication with your server, it wouldn’t make much sense if we.
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.
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:
