ssh: Generate an ed25519 key with 100 key derivation function rounds and save the key to a specific file.

ssh-keygen

$ ssh-keygen -t ${ed25519} -a ${100} -f ${~--ssh-filename}

try on your machine

This command creates a new SSH key pair using the ssh-keygen tool. Let's break down the options and parameters used in this command:

ssh-keygen: It is the command-line tool used to generate SSH keys.
-t ${ed25519}: This option specifies the type of the key algorithm to be generated. In this case, it is ed25519, which is a popular elliptic curve algorithm.
-a ${100}: This option sets the number of key derivation function rounds used. In this example, it is set to 100.
-f ${~--ssh-filename}: This option determines the file name for the generated key file. The ~ symbol denotes inserting the user's home directory path. The --ssh-filename part refers to a variable or placeholder for the desired file name.

Overall, this command generates a new SSH key pair using the ed25519 algorithm, with 100 rounds of key derivation function, and saves the key files using the provided file name.
