Our Lead API(s) leverage SSL (Secure Socket Layer) for encryption, the communication between the client and the server is secured using an encryption-decryption mechanism to ensure data confidentiality and integrity. SSL operates in the transport layer, encapsulating higher-level protocols such as HTTP. When a client establishes a connection to an SSL-enabled server, they perform an SSL handshake. During this handshake, both parties agree on a version of SSL/TLS (Transport Layer Security, the successor to SSL) to use, select cryptographic algorithms, and exchange cryptographic keys. The client and server will then use these keys to symmetrically encrypt and decrypt the transmitted data, ensuring that any eavesdropper intercepting the data in transit cannot easily decipher it. Additionally, SSL provides server authentication through the use of digital certificates, allowing clients to verify the identity of the server, ensuring they are communicating with the intended recipient and not a malicious actor. This combination of encryption, data integrity, and authentication provides a robust security framework for RESTful API communications over potentially insecure networks.
