Every single DevOps engineer needs to use SSH essential-primarily based authentication when working with Linux servers. Also, most cloud platforms provide and recommend SSH important-centered server authentication for Increased protection
Imagine it just like a keychain. In combination with Keeping private keys it also brokers requests to indicator SSH requests While using the personal keys so that personal keys are by no means handed around unsecurly.
When a person requests to connect to a server with SSH, the server sends a information encrypted with the general public key that will only be decrypted by the associated personal essential. The person’s area equipment then makes use of its private critical to make an effort to decrypt the message.
