ECC is an alternative option to the RSA algorithm. ECC carries faster, shorter keys and consumes fewer computer resources. However, the key size increases to provide maximum protection by the time the key size increases, which puts an extra burden on the computer system. As a result, the ECC algorithm came into force with more minor keys; for example, the 3072-bit RSA key is equal to the 256-bit ECC key. Take note that both RSA and ECC keys offer the same security.
