The industry is now requiring TLS 1.2 as a secure protocol for https communications. Soon the API's you may be using for UPS, USPS, FedEx, Authorize.net, PayPal and more will no longer accept connections on the older TLS. This creates many challenges for developers and website owners worldwide. TLS (Transport Layer Security) 1.2 is a cryptographic protocol that provides secure communication over the internet. It is widely used to encrypt web traffic and other sensitive data transmitted over the internet. TLS 1.2 is designed to protect the confidentiality and integrity of data being transmitted over the internet by encrypting the data in transit. It uses a combination of public and private key encryption to establish a secure connection between two parties, such as a web server and a client. Once a secure connection has been established, the data being transmitted is encrypted and can only be decrypted by the intended recipient using the private key. This helps to prevent unauthorized access to the data, even if the data is intercepted during transmission. TLS 1.2 also includes other security features, such as certificate-based authentication, to help ensure that the identity of the parties involved in the communication can be verified. In summary, TLS 1.2 is a widely-used security protocol that provides secure communication over the internet by encrypting data in transit and verifying the identity of the parties involved in the communication.
