Secure Socket Layer (SSL) andTransport Layer Security (TLS) are both protocols that provide secure communication over the internet.They are used to encrypt data that is transmitted between two parties, such as a web browser and a web server While SSLwas the original protocol, it has been largely replaced byTLS, which is considered more secure. In this blog, we'll explore the differences between SSLandTLS, and discuss which protocol is better for securing your online communications
What is Secure Socket Layer (SSL)?
Secure Socket Layer (SSL) is a protocol that was developed by Netscape in the mid-1990s to provide secure communication over the internet. It was designed to encrypt data that was transmitted between two parties, such as a web browser and a web server SSLuses a combination of public-key and symmetric-key encryption to ensure that data is transmitted securely
SSLworks by establishing a secure connection between the client and the server.The client sends a request to the server, and the server responds by sending its SSLcertificate to the client The client verifies the certificate, and if it is valid, it generates a unique session key that is used to encrypt and decrypt data during the session.
What isTransport Layer Security (TLS)?
Transport Layer Security (TLS) is a successor to SSLthat was developed by the Internet EngineeringTask Force (IETF) in the late 1990s. Like SSL,TLS is designed to provide secure communication over the internet It uses a combination of public-key and symmetric-key encryption to ensure that data is transmitted securely.
TLS works in a similar way to SSL When a client requests a secure connection, the server sends itsTLS certificate to the client.The client verifies the certificate, and if it is valid, it generates a unique session key that is used to encrypt and decrypt data during the session
What are the differences between SSLandTLS?
While SSLandTLS are similar in many ways, there are some key differences between the two protocols
1. Security:TLS is generally considered more secure than SSL.This is becauseTLS has stronger encryption algorithms, and it is less vulnerable to attacks such as POODLE and BEAST
2 Compatibility:TLS is backward compatible with SSL, which means that it can be used with older web browsers that don't support the latest SSLprotocols SSL, on the other hand, is not compatible withTLS.
3. Protocol Versions: SSLhas four versions (SSLv2, SSLv3,TLSv1.0,TLSv1.1), whileTLS has three versions (TLSv1 0,TLSv1 1,TLSv1 2) SSLv2 and SSLv3 are no longer considered secure and should not be used
4 Handshake Process:The handshake process inTLS is slightly different than in SSL TLS uses a different cipher suite negotiation process, and it includes support for Perfect Forward Secrecy (PFS).
5. Implementation:TLS is generally more widely implemented than SSL.This is because SSL has been largely replaced byTLS, and most web browsers and servers now supportTLS.
Which is better: SSLorTLS?
TLS is generally considered to be better than SSLfor securing online communications This is becauseTLS is more secure, more widely implemented, and more compatible with modern web browsers and servers In addition,TLS includes support for Perfect Forward Secrecy (PFS), which provides an additional layer of security by generating a new session key for each session
While SSLis still used in some legacy systems, it is not recommended for use in new systems
If you are currently using SSL, it is recommended that you upgrade toTLS as soon as possible to ensure that your online communications are secure
In conclusion, SSLandTLS are both protocols that provide secure communication over the internet While SSLwas the original protocol, it has been largely replaced byTLS, which is considered more secure.TLS is more widely implemented, more compatible with modern web browsers and servers, and includes support for Perfect Forward Secrecy (PFS) If you are currently using SSL, it is recommended that you upgrade toTLS as soon as possible to ensure that your online communications are secure.
