WebbSM2 is based on ECC(Elliptic Curve Cryptography), and uses a special curve. It can be used in digital signature, key exchange and asymmetric cryptography. For key exchange, SM2 is similar to ECDH, but involves new random key, meaning the two sides need to exchange extra random public key besides their public key, that's why additional APIs are needed … Webbdef _sn_to_elliptic_curve (backend: Backend, sn: str) -> ec.EllipticCurve: try: return ec._CURVE_TYPES [sn] () except KeyError: raise UnsupportedAlgorithm ( f" {sn} is not a supported elliptic curve", _Reasons.UNSUPPORTED_ELLIPTIC_CURVE, ) def _ecdsa_sig_sign ( backend: Backend, private_key: _EllipticCurvePrivateKey, data: bytes ) …

"Webb9 juni 2024 · As far as current standards of security are concerned, there’s not much of a point of the “ECDSA vs. RSA” debate as you can choose either of them as they both are entirely secure. I’d like to reiterate the face that the ECC isn’t as widely supported as RSA. Having said that, if you have the option to select, ECC is a better option. " - Sm2 is not a supported elliptic curve

WebbECC (Elliptic Curve Cryptography) is a modern and efficient type of public key cryptography. Its security is based on the difficulty to solve discrete logarithms on the field defined by specific equations computed over a curve. ECC can be used to create digital signatures or to perform a key exchange.
