不是很理解你的问题,这个包没有定义自己的公钥数据结构啊。感觉你的两个case可以合并成一个:
case *ecdsa.PrivateKey,*sm2.PrivateKey:
from gmsm.
是的,先前依赖的tjfoc/gmsm
没有定义自己的公钥数据结构,代码可读性会显得有点怪
比如这个,明明是sm2,单看函数签名却是ecdsa
// FromsPub 公钥 -> []byte
func FromsPub(pub *ecdsa.PublicKey) []byte {
if pub == nil || pub.X == nil || pub.Y == nil {
return nil
}
return elliptic.Marshal(pub.Curve, pub.X, pub.Y)
}
// ToPub []byte -> 公钥
func ToPub(pub []byte) *ecdsa.PublicKey {
if len(pub) == 0 {
return nil
}
curve := sm2.P256()
x, y := elliptic.Unmarshal(curve, pub)
return &ecdsa.PublicKey{Curve: curve, X: x, Y: y}
}

SM2曲线和NIST P-256只是参数不同而已,所以数据结构是一样的,就象NIST P-224 P-256 P-384 P-512,SM2曲线无需扩展此结构也没有SM2曲线特殊的方法需要实现。还有就是考虑SM2-256曲线理论上是和SM2加解密、签名验签算法分开的,其实无需深度绑定。你的ToPub方法,如果加上curve参数,其实是适用所有NIST P系列和SM2 256曲线的。
