从VB.NET创建的解密RSA [XML]

Question

我尝试使用phpseclib加密/解密在VB.NET中加密的字符串，当我试图从VB.NET解密RSA XML时，我没有遇到任何错误，只是一个空白页面。

这里是VB.NET创建的XML键：

正常工作：

<?php 
include('Crypt/RSA.php'); 

$rsa = new Crypt_RSA(); 
$rsa->loadKey('<RSAKeyValue><Modulus>qfOIjoSxsmBqS3YGsxd4+FBEmFmX4Z/cTAV4l3BOqmMVDxTxHt4QuvK8l2Iv6GeTSp5xuwpqUkgwyo4zb2UQt1sLn2vvAmGqz7Oih6gHYrpA9GmR6QHomsQNJrDTvZXtCPNUmWZ5DzFjnKNL/FfZQGYp0qjIkpIhuLAUhKYzMaM=</Modulus><Exponent>AQAB</Exponent><P>57hBPSAr6VGVYTYL6pUft0y9hbU7cUYEiYhF2pVJ0pv6pGWIb27nK+9U/AaWH0+wtefpRlVyjbeNiDK3rmYmtQ==</P><Q>u8Jgam1//jhcYYCZX5168L0roe6L+IJ0A98zlbQb7crpqbTxqDAsX9LQpGiQP1JZINowAbPECDRZIGfT+fsV9w==</Q><DP>AZASkJD4+tfcBA3TQr/CuP/Bf3dbcUYhnbPXlMPQ/aSjqhwtMWM0F+3DSvfYZ1moPXHU9u54mVAVmkeNSZXSyQ==</DP><DQ>J1DFVaPGKFpu5a/C7eWQ57YE2+ySfJ/8YQ8sww0qx/k0Qmf0Li6gLBR9wd9vTQMWTK3DXafhxYIIo6N6HJ858w==</DQ><InverseQ>Q2MlSoE2ADtFXvjPi5UgxApqp4QewmZONu3vGmAL07JMyDHdgVweevZTJTun3EBRKV0PWCMvtk4BJW0lUSuBNQ==</InverseQ><D>TCzzVWYWu+xJWJ+DazynJS3dQShPUnsz5ANDxSU6rVaR9tudJAfHGfR5IaWJ8bKTK4wPUBXgCBeBfxjz5wc20SyBWa1vL7K4DqLRJ/qEyFSZxXr8wKQOKyexZRGbsLjtUnmYrrXKMOhRkiV/VI1K+TKX/FhoDVPjz8s4GamzNQk=</D></RSAKeyValue>'); 

$rsa->setEncryptionMode(CRYPT_RSA_ENCRYPTION_PKCS1);

phpseclib已内置在一段时间内支持XML密钥，所以你不需要跳过所有的h哎呀，你在你的代码中做了。

明文是h e l l o。如果你还没有，请确保你正在运行最新版本的phpseclib。我不知道使用旧版本会引起问题，但运行最新版本无论如何都不是一个坏主意。
