What is TLS?
Transport Layer Security (TLS) is a cryptographic protocol utilized for secure communication between systems. It succeeded the Secure Sockets Layer (SSL) protocol in 2000. TLS has undergone several versions, including TLS v1.0, v1.1, v1.2, and v1.3.
Why is it important?
TLS ensures that data transmitted over a network remains confidential and integral. It protects against eavesdropping, tampering, and forgery of transmitted data. Compliance standards like PCI DSS mandate the use of modern TLS versions (v1.2 and above) due to vulnerabilities in older versions.
How does it impact me?
To access the Open Payment Platform and other online services securely, customers must support at least TLS v1.2. TLS v1.0 and v1.1 have been disabled since 2018 due to security concerns. Users need to use TLS v1.2 or v1.3 compatible browsers to continue accessing these services. TLS v1.3 is recommended for improved performance during the handshake process.
