ssh:files:user-rights:set
The command "chmod 600 ~/.ssh/id_rsa" is used to change the access permissions for the private key file "id_rsa" located in the "~/.ssh" directory.
More specifically, "chmod" is a command used in Linux and Unix-based systems to modify file permissions.
"600" is the permission code that is being set or applied to the specified file. In this case, "600" indicates that the file owner has read and write permissions for the file, while all other users have no permissions (no read, write, or execute permissions).
"~/.ssh/id_rsa" is the path to the private key file that is being modified. The "~" represents the user's home directory, and ".ssh" refers to the hidden folder that typically contains SSH-related files.
By setting the permissions of the private key file to "600", the command ensures that only the owner of the file can read and modify it, adding an extra layer of security to prevent unauthorized access to the SSH private key.
