RSA Encryption in C#: How It Works

RSA encryption is a type of asymmetric encryption algorithm that utilizes public and private keys for encryption and decryption. The encryption process of the RSA algorithm proceeds as follows:

1. Create a public and private key pair: First, generate a pair of public and private keys. The public key is used to encrypt data, while the private key is used to decrypt data.
2. Encrypting data involves using the recipient’s public key to encrypt the data that needs to be transmitted. The encrypted data can only be decrypted using the recipient’s private key.
3. Decrypt data: The recipient decrypts the received encrypted data using their own private key, obtaining the original data.

The security of the RSA algorithm is based on the difficulty of factoring large numbers, meaning it is easy to multiply two large prime numbers to get a large number, but extremely difficult to find the original two prime numbers from that large number. This difficulty ensures the security of the RSA algorithm.
