Encrypted Protocols
Encrypted protocols are communication protocols that use cryptographic techniques to secure data transmission over networks, ensuring confidentiality, integrity, and authentication. They protect sensitive information from eavesdropping, tampering, and unauthorized access by encrypting data at the sender's end and decrypting it at the receiver's end. Common examples include HTTPS, TLS/SSL, SSH, and IPsec, which are fundamental to secure internet communications, online transactions, and remote access.
Developers should learn and use encrypted protocols whenever handling sensitive data, such as in web applications, APIs, financial systems, or healthcare platforms, to comply with security standards (e.g., GDPR, HIPAA) and prevent data breaches. They are essential for implementing secure authentication, protecting user privacy, and building trust in digital services, especially in scenarios involving public networks, cloud deployments, or IoT devices where data interception risks are high.
