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.
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.Create a URL Signature Using Java In addition to the following code example, you can use the CloudFrontUrlSigner utility class in the AWS SDK for Java (version 1) to create CloudFront signed URLs. Oct 31, 2018 The method again uses the static SECRETKEY property to generate the signing key, and uses that to verify that the JWT has not been tampered with. The method will throw io.jsonwebtoken.SignatureException exception if the signature does not match the token. If the signature does match, the method returns the claims as a Claims object.

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. May 28, 2019 But for the signing process we’ll only use the private key. While the public key will be use to verify the signature. To create a digital signature we need an instance of java.security.Signature. To get one we can call the Signature.getInstance method. Apr 23, 2012 Use the Java keytool to create public and private keys for RSA authentication if the client is in Java. Generating a RSA Key with the Java Keytool Use the Java keytool to create public and private keys for RSA authentication if the client is in Java.
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:
