Which is better, Rsa dsa ecdsa?
RSA is the most widely used and classic digital signature encryption algorithm at present, but the signature is long,

It is very troublesome to generate keys, and the technology of prime number generation is limited, so it is difficult to achieve one secret at a time.

ECDSA has a strong development momentum and an upward trend. ECDSA algorithm is a combination of ECC and DSA. Compared with RSA digital signature algorithm, ECdsa algorithm has the advantages of high speed, high strength, short signature and optimistic prospect.
