Text to Encrypt

RSA is designed for small data. For larger content, consider using hybrid encryption (RSA + AES).

Note: RSA is an asymmetric encryption algorithm that uses a pair of keys. The public key can be shared and is used for encryption, while the private key must be kept secret and is used for decryption.
