advantage:
Compared with the traditional digital signature algorithm, it has high speed, high strength and short signature.

RSA, DSA, and ECDSA
are classic algorithms and are by far the most widely used digital signature algorithms.
The key implementation of the RSA digital signature algorithm is the same as the RSA encryption algorithm, and the algorithm name is called RSA. The key generation and conversion are the same.
RSA digital signature algorithms mainly include MD and SHA.
DSS (Digital Signature Standard): The digital signature standard
gradually formed the DSA algorithm on the basis of DSS.
DSA (Digital Signature Algorithm): digital signature algorithm
DSA only contains digital signatures. Certificates using DSA algorithms cannot perform encrypted communications.
But RSA contains both digital signature algorithms and encryption and decryption.
The serial number verification algorithm of Microsoft products uses ECDSA.
ECDSA (Elliptic Curve Digital Signature Algorithm): Elliptic curve digital signature algorithm
