What mechanism does the Chef Infra Client use to secure connections when pulling configurations?

The Chef Infra Client secures connections when pulling configurations primarily through the use of HTTPS encryption. This encryption protocol ensures that data transmitted between the Chef Infra Client and the Chef Infra Server is protected from eavesdropping and tampering. HTTPS uses TLS (Transport Layer Security) to encrypt the communication channels, providing a secure method for the client to receive configuration data and recipes from the server.

While SSH keys, RSA protected connections, and JWT tokens are valid security mechanisms in various contexts, they are not the primary method employed by the Chef Infra Client for securing its communications. SSH keys are typically used for secure shell access rather than for configuration data transfer, while RSA connections might refer to specific cryptographic implementations that are not necessarily the standard in Chef's architecture. JWT tokens are often used for authentication purposes in web applications but do not apply to the Chef communication framework in the way that HTTPS does.

Therefore, HTTPS encryption is the fundamental mechanism that ensures the integrity and confidentiality of the data being communicated between the Chef Infra Client and Chef Infra Server.
