This command is used to change the passphrase of an SSH private key. Let's break down the elements of the command:
ssh-keygen: It is the command-line utility for generating and managing SSH keys.-p: This flag is used to specify that the command is meant for changing the passphrase of the key.-N "": This flag sets an empty passphrase, effectively removing the requirement for a passphrase. By default, thessh-keygencommand prompts for a new passphrase, but the""value ensures an empty passphrase is set.-m ${PEM}: This flag specifies the key format to use. The${PEM}variable contains the value of the desired format, which could be PEM or PKCS8.-f ${~--ssh-OpenSSH_private_key}: This flag is used to specify the path and name of the private key file. The${~--ssh-OpenSSH_private_key}is a variable that should contain the path to the private key file.
In summary, this command changes the passphrase of the SSH private key file specified by the ${~--ssh-OpenSSH_private_key} variable to an empty passphrase, using the specified key format ${PEM}.
