TLS/HTTPS varmennus, also known as Transport Layer Security (TLS) and Hypertext Transfer Protocol Secure (HTTPS), is a protocol used to secure data transmitted over the internet. It ensures that data is encrypted and protected from eavesdropping, tampering, and message forgery. TLS/HTTPS is widely used to secure web communications, including online banking, e-commerce, and social media platforms.

The protocol works by establishing a secure connection between a client (such as a web browser) and a server. This connection is secured through the use of digital certificates, which are issued by trusted Certificate Authorities (CAs). These certificates verify the identity of the server and establish a secure channel for data transmission.

TLS/HTTPS provides several key benefits:

1. Data Encryption: Ensures that data transmitted between the client and server is encrypted, making it unreadable to unauthorized parties.

2. Data Integrity: Guarantees that the data has not been altered during transmission.

3. Authentication: Verifies the identity of the server, preventing man-in-the-middle attacks.

The process of establishing a TLS/HTTPS connection involves several steps, including the exchange of cryptographic keys, the verification of digital certificates, and the negotiation of encryption algorithms. Once the connection is established, all data transmitted between the client and server is encrypted and secure.

TLS/HTTPS is a critical component of modern internet security, protecting sensitive information and ensuring the integrity and confidentiality of online communications. Its widespread adoption has significantly reduced the risk of data breaches and cyber attacks, making it an essential tool for both individuals and organizations.
