Keeping text messages secure from hackers and eavesdroppers is increasingly important. Governments seek access to these messages to investigate criminals and terrorists, while tech companies argue this could infringe on privacy. Text messages use end-to-end encryption, ensuring data is kept private during transmission. This process involves two unique keys: a public key, shared with others for encryption, and a private key, which remains on the user's device and is never shared. When two individuals communicate securely, they create a temporary shared key by combining their public and private keys, facilitating encrypted messaging.
