将RSA公钥和私钥导入VB.NET

我对RSA加密有点陌生。我使用PGPfreeware 6.5.8创建了一个RSA密钥对，我正在编写一个VB.NET代码，用于加密和解密XML文件中的字段。我导出了包含公钥和私钥的RSA密钥，文件扩展名为.asc（ASCII）。我得到了这种格式的公钥和私钥：

当我试图将公钥和私钥传递给我的RSACryptServiceProvider对象时，我发现这些密钥的形式是.NET无法处理的。NET只处理XML公钥和私钥。我在互联网上搜索，发现这种格式的键是使用Base64转换原始文本的结果，所以我尝试将它们转换回正常文本，而不是Base64文本，这样我就可以——希望如此——将它们导入到我的对象中，但我得到一个FormatException，说：Base-64字符串中的字符无效。我做错了什么？如何使文件作为RSA对象的公钥和私钥工作

谢谢。

格式不兼容远远超出了base64（实际上是ascii）编码；OpenPGP密钥格式基本上与.Net支持的任何格式都不兼容。有一个用C#编写的第三方库叫做Bouncycastle，它可以提供帮助，但显然不是VB。我在互联网上搜索时看到了这个库（Bouncycastle）和其他一些库，但我仍在寻找是否有办法将文件格式转换为可读的XML格式（这与您现在的答复不符），或者使用与VB.NET兼容的新的第三方应用程序生成RSA密钥。感谢您的答复。
