SM2CurveUtils.SM2_CURVE

SM2CurveUtils.SM2_CURVE refers to the elliptic curve used in the SM2 cryptographic algorithm. The SM2 algorithm is a widely used cryptographic algorithm in China, and is based on the elliptic curve cryptography (ECC) algorithm. The SM2 curve is defined as follows:

- Field: GF(p), where p is a large prime number (256-bit or 512-bit)
- Curve equation: y^2 = x^3 + ax + b (mod p), where a and b are constants chosen to satisfy certain properties (e.g., being non-zero and not equal to each other)
- Base point: a specific point on the curve that is used as a starting point for cryptographic operations

The SM2 curve has been chosen carefully to provide strong security properties while also being efficient to compute on. It is designed to resist various attacks, such as the elliptic curve discrete logarithm problem (ECDLP) and the side-channel attacks. The SM2 algorithm is used in various applications, such as digital signatures, key exchange, and encryption.
