Thus, the router IPsec can be configured without IKE, but IKE enhances IPsec by providing additional features, flexibility, and ease of configuration Enters public key chain configuration mode (so you can manually specify the RSA public keys of other devices).

Unlike RSA signatures, the RSA encrypted nonces method cannot use certificates to exchange public keys. secure than DES: AES offers a larger key size, while ensuring that the only known approach to decrypt a message is for an implementation.
