.net-core - BouncyCasSTLe.NetCore : Impossible to find the CryptoApiRandomGenerator class

Question

我已经安装了 BouncyCaSTLe.NetCore 包来创建自签名证书，但我找不到 CryptoApiRandomGenerator 类。

正常吗？如果是，替代品是什么？

您可以实现自己的 CryptoApiRandomGenerator。像这样的事情:

public class MyCryptoApiRandomGenerator
    : IRandomGenerator
{
    private readonly RNGCryptoServiceProvider rndProv;

    public NetMatchCryptoApiRandomGenerator()
    {
        rndProv = new RNGCryptoServiceProvider();
    }

    #region IRandomGenerator Members

    public virtual void AddSeedMaterial(byte[] seed)
    {
        // I don't care about the seed
    }

    public virtual void AddSeedMaterial(long seed)
    {
        // I don't care about the seed
    }

    public virtual void NextBytes(byte[] bytes)
    {
        rndProv.GetBytes(bytes);
    }

    public virtual void NextBytes(byte[] bytes, int start, int len)
    {
        if (start < 0)
            throw new ArgumentException("Start offset cannot be negative", "start");
        if (bytes.Length < (start + len))
            throw new ArgumentException("Byte array too small for requested offset and length");

        if (bytes.Length == len && start == 0)
        {
            NextBytes(bytes);
        }
        else
        {
            byte[] tmpBuf = new byte[len];
            rndProv.GetBytes(tmpBuf);
            Array.Copy(tmpBuf, 0, bytes, start, len);
        }
    }

    #endregion
}

目前 .Net Core 中还没有隐式实现。
