C＃.NET 生成非xml rsa公钥和私钥：

 CspParameters cspParams = new CspParameters { ProviderType = 1 };
 System.Security.Cryptography.RSACryptoServiceProvider rsa = new                 System.Security.Cryptography.RSACryptoServiceProvider(1024, cspParams); 
 // Generate a new 2048 bit RSA key

 String public_key = Convert.ToBase64String(rsa.ExportCspBlob(false));
 String private_key = Convert.ToBase64String(rsa.ExportCspBlob(true));

请帮助我，为什么数据不使用c＃公钥和私钥在php中加密和解密..

Answer 1

您正在使用两种不同版本的phpseclib。对于解密，您使用的是1.0分支，对于加密，您使用的是2.0或主分支。

所以我建议首先使用相同的版本。
使用常量而不是它们对应的整数也是好的。例如。不要$rsa->setEncryptionMode(2) - 做$rsa->setEncryptionMode(Crypt\RSA::ENCRYPTION_PKCS1)。至少是您的第一个包含工作代码的代码段。
对于您的第二个代码段，您使用的phpseclib版本与第一个代码段不同...您的密钥无效。

它们以BgIAAACkAAB和BwIAAACkA ...键开头，以-----BEGIN PUBLIC KEY-----或-----BEGIN RSA PRIVATE KEY----- 开头，以{{}开头1}}或MIICXAIBAAKB。 https://stackoverflow.com/a/21289989/569976提供了更详细的解释原因。

您的密钥似乎所处的格式（并且您似乎已尝试改变为phpseclib支持的格式）实际上是Microsoft Key BLOB。我在这里写了一个初步解码器：

https://stackoverflow.com/a/32486709/569976

将它扩展到phpseclib核心会更好，但我们会看到。
