在这里生成 RSA 数字时，我不能总是得到正确的数字，所以我使用这个网站来检查我是否得到了正确的 RSA 数字，并且 D 和指数不 = 0
指数=e
每次我得到 Exponent 和 D 时，我都会使用这个网站检查 P、Q、Exponent 和 D 以确保它是正确的

如果可以尝试检查这里的编码，也许这个地方是我做错的地方
我最初想到使用 BitCoverter.GetBytes() 来转换 long 和 Ulong 数据类型值
但最后，bitconverter.getbytes() 对我不起作用，所以我必须首先将所有这些 long 和 ulong 数据类型值转换为字符串，然后使用 BYTE.PARSE() 将字符串转换为字节值
我就是这样做的
如果让我们这里的任何专家确认上面的编码有效并且所有值都是正确的，那么尝试检查这里是否有任何潜在的错误

我在生成按钮中尝试做的是为 RSA 创建合适的参数。
我实际上能够生成它们的参数，但可以是 ULong 或 Long 数据类型。
当我第一次将它们转换为字节数组时，我考虑过使用 BitConverter，但至少在我的情况下它不起作用。
我只能将它们变成字节数组的唯一方法是将 ULong 或 Long 数据类型变量变成字符串。
然后将这些字符串转换为 Byte，然后将它们放入 ByteArray 我希望它是正确的，但现在我无法做到。
关于如何使参数数据被接受为 rsa 参数的任何想法？
