RSA encryption is a widely used cryptographic algorithm for securing data transmission over insecure networks. In RSA encryption, data is encrypted with a public key and can only be decrypted with the corresponding private key. In this guide, we'll explore how to decrypt RSA encrypted data using Java's private key.

Generate Key Pair
First, you need to generate an RSA key pair containing a public key and a private key. This can be achieved using Java's KeyPairGenerator class.

Load Private Key
If you already have a private key stored in a file or obtained from another source, you can load it into your Java application.
