What is id_rsa? Unverified

Understanding the id_rsa file and its role in SSH authentication.

No confirmed answer yet. Below is what is and isn't known. We'd rather be honest than invent a figure โ€” this becomes a full Community Q&A answer the moment we can back it with our data.

What is id_rsa?

id_rsa is a file that typically contains a user's private SSH key, which is used for secure shell (SSH) authentication. This key is part of a key pair, which also includes a public key (often named id_rsa.pub). The private key should be kept secure and never shared, while the public key can be distributed to servers to grant access.

The specific details about the creation, management, or security practices surrounding id_rsa files are not covered in the provided knowledge base.
