TLS

Ques:- What is forward secrecy in TLS and why is it important

Asked In :- province of new brunswick,

Right Answer:
Forward secrecy in TLS is a feature that ensures session keys are not compromised even if the server's private key is later exposed. It achieves this by generating unique session keys for each session, using ephemeral key exchanges. This is important because it protects past communications from being decrypted, enhancing overall security and privacy.

TLS

Ques:- What is TLS and how does it work

Asked In :- Nalsoft, province of new brunswick,

Right Answer:
TLS (Transport Layer Security) is a cryptographic protocol designed to provide secure communication over a computer network. It works by establishing a secure connection between a client and a server through the following steps:

1. **Handshake**: The client and server exchange messages to agree on encryption methods and authenticate each other.
2. **Session Keys**: They generate session keys for encrypting the data during the session.
3. **Secure Communication**: Once the secure connection is established, data is encrypted and transmitted, ensuring confidentiality and integrity.
4. **Termination**: The session can be securely closed when communication is complete.

TLS

Ques:- What is the difference between TLS 1.0, 1.1, 1.2, and 1.3

Asked In :- Nalsoft, Webtech Developers, Relinns Technologies, province of new brunswick,

Right Answer:
TLS 1.0, 1.1, 1.2, and 1.3 are versions of the Transport Layer Security protocol, each improving security and performance:

- **TLS 1.0**: Introduced in 1999, it has known vulnerabilities and is considered insecure.
- **TLS 1.1**: Released in 2006, it addressed some vulnerabilities of 1.0 but is still outdated.
- **TLS 1.2**: Introduced in 2008, it supports stronger encryption algorithms and is widely used today.
- **TLS 1.3**: Released in 2018, it simplifies the handshake process, improves security, and reduces latency, making it the most secure and efficient version.

TLS

Ques:- What is the difference between TLS and HTTPS

Asked In :- Mitsogo Technologies, province of new brunswick,

Right Answer:
TLS (Transport Layer Security) is a cryptographic protocol that provides secure communication over a network, while HTTPS (Hypertext Transfer Protocol Secure) is an application layer protocol that uses TLS to secure HTTP traffic. In essence, HTTPS is HTTP over TLS.

TLS

Ques:- What is the role of the public and private keys in TLS

Asked In :- Nalsoft, Eidiko Systems Integrators, Relinns Technologies, province of new brunswick,

Right Answer:
In TLS, the public key is used to encrypt data that only the holder of the corresponding private key can decrypt. The private key is kept secret by the server and is used to decrypt the data sent by clients, as well as to create digital signatures that verify the server's identity.
