sudo chmod 600 ~/.ssh/key.pem
Note that Linux SSH manual says:
~/.ssh/: This directory is the default location for all user-specific configuration and authentication information. There is no general requirement to keep the entire contents of this directory secret, but the recommended permissions are read/write/execute for the user and not accessible by others. (Recommends 700)~/.ssh/id_rsa: Contains the private key for authentication. These files contain sensitive data and should be readable by the user but not accessible by others (read/write/execute). ssh will simply ignore a private key file if it is accessible by others. It is possible to specify a passphrase when generating the key, which will be used to encrypt the sensitive part of this file using 3DES. (Recommends 600)No comments yet.
