Performing asymmetric encryption in Java
- [Narrator] Now that we have a key pair, it's time to implement our encryption and decryption routines using RSA. Let's jump back into our IDE and open up source main Java. And now, this time, our asymmetric package and open up our asymmetric encryption utils. Now to this class, let's go ahead and add a method. Public static byte array called performRSAEncryption, and we will pass it a string in a plain text, and a private key. And this method will throw an exception. Now much like we saw for the symmetric routine, we are gonna create an instance of a cipher, cipher.getInstance, and we're gonna pass it our RSA algorithm. Now this time there's no padding or CBC because it's not a block cipher, there's no padding, we don't need to deal with any of that this time. But we will go ahead and create a cipher.init, using the encrypt mode, and our private key. And now our final step here is to return the…
