Generate an RSA SSH keypair with a 4096 bit private key
ssh-keygen -t rsa -b 4096 -C "RSA 4096 bit Keys"
Generate an DSA SSH keypair with a 2048 bit private key
ssh-keygen -t dsa -b 1024 -C "DSA 1024 bit Keys"
Generate an ECDSA SSH keypair with a 521 bit private key
ssh-keygen -t ecdsa -b 521 -C "ECDSA 521 bit Keys"
Generate an ed25519 SSH keypair- this is a new algorithm added in OpenSSH.
ssh-keygen -t ed25519
Extracting the public key from an RSA keypair
openssl rsa -pubout -in private_key.pem -out public_key.pem
Extracting the public key from an DSA keypair
openssl dsa -pubout -in private_key.pem -out public_key.pem
Copy the public key to the server
The ssh-copy-id command
ssh-copy-id user@hostname copies the public key of your default identity (use -i identity_file for other identities) to the remote host
SSH Running on different port
ssh-copy-id -i "user@hostname -p2222"
-i switch defaults to ~/.ssh/id_rsa.pub, if you want another key, put the path of the key after
Converting keys between openssl and openssh
Extract Public key from the certificate
openssl x509 -in cert.pem -noout -pubkey >pubkey.pem
cat pubkey.pem
