Secure messaging refers to the use of technology to send messages that are protected from unauthorized access. This is crucial in today's digital age, where privacy concerns are paramount. Secure messaging applications often employ encryption methods to ensure that only the intended recipient can read the messages, safeguarding sensitive information from potential threats. Many secure messaging platforms, such as Signal and WhatsApp, offer end-to-end encryption, meaning that messages are encrypted on the sender's device and only decrypted on the receiver's device. This level of security helps protect personal conversations, business communications, and other confidential exchanges from interception and eavesdropping.
