RSA encryption is a widely used public-key cryptosystem that is fundamental to many mobile app security features. It relies on the mathematical difficulty of factoring large numbers. Here's how it works:

1. Key Generation: Each user generates a pair of keys: a public key and a private key. The public key is made available to anyone who wants to send an encrypted message, while the private key is kept secret.
2. Encryption: To encrypt a message, the sender uses the recipient's public key. This process transforms the message into ciphertext, which is an unreadable form.
3. Decryption: The recipient uses their private key to decrypt the ciphertext, transforming it back into the original message. Only the holder of the private key can decrypt the message.

In mobile apps, RSA is commonly used for:

• Secure Communication: Encrypting data sent between the app and the server, protecting sensitive information during transmission.
• Digital Signatures: Ensuring the authenticity and integrity of data. The sender uses their private key to create a digital signature, and the recipient uses the sender's public key to verify the signature.
• Key Exchange: Securely exchanging symmetric encryption keys. RSA is often used to encrypt a smaller, faster symmetric key which is then used to encrypt larger amounts of data. This is more efficient than using RSA for the entire data transfer.

The implementation specifics vary depending on the app's architecture and the chosen security libraries. However, the core principles of RSA encryption remain the same.
