generate a new 4096 bit SSH key that uses RSA algorithm
Raw
gen-rsa-ssh-key.sh
# Generate new 4096 bit RSA SSH key:
# --- Only use when ed25519 isnt possible ---
ssh-keygen -o -a 100 -t rsa -b 4096 -f ~/.ssh/id_rsa -C "login@hostname.com"
# -o : Save the private-key using the new OpenSSH format rather than the PEM format
# -a: Increase resistance to brute-force password cracking if the private-key is stolen.
# -t: Type of key to create (rsa).
# -f: Filename of the generated key file.
# -C: Optional comment, often <login>@<hostname> or email.
