请问怎么解决 --------------------编程问答-------------------- _result是什么结果？！ --------------------编程问答--------------------

大神 还在吗？

没用过这种加密，爱莫能助啊！！ 可以考虑使用其它加密方式

楼主提供的密钥只是公钥，但正确用法是公钥私钥都要包含在里面的。下面是例子：
<RSAKeyValue><Modulus>uJikVPTRj2m7lg3SBFxQ3HEtap8y3MzKtUW4vhLelnvhhrBdUVusNYog9cIPODMhVRtyUev7Kqqr7E5z0zn8vjhfDLSkT0VYli3ZmDRr/JZZ343TVaqObxG6ZEZHVXzYBZ+pb0aHzR39nk002LGtFM/Qet4vOACqaASAHwvZjv8=</Modulus><Exponent>AQAB</Exponent><P>6IgQk8tQY1/AmeYJQT4vIuzVrfAcI8PR2ELfMD05bBrqZ6PjQWdp/gIlYsLq/VL9loxREDd/jY/ThprDymmraQ==</P><Q>yzoSAq7rUlNxr/Pmr8/f9VpaiBNCXcjdmmFut7Rv2v4HYMNOAXOQG1NQCdi4f2VcriZ2a9CbcvlvL/t7nAiiJw==</Q><DP>nd9bWeyMzJtC+XnryKb+e7jOLoS5pjKZ8zkbrPW0WchAY1MqxMoAdVthpJbv0kQZNbBYjSkQ6by/gUDsMy3hGQ==</DP><DQ>rqU41RV9JUKQcKUpme0Kic8b/dSPNAlqZ0FT5IsrlQa5UG6Gmri1HsZ6Afw8kT6KZx6mpgCfli7FXna/w1eoAQ==</DQ><InverseQ>1MAM8T2f/Xjfbz/ZVK6p/smx5RUmjBxdoFkGVMjEc0iY3UwmEnwOokRiLLDWgXlmqHS08Cb02BRnTQhK5sNLbw==</InverseQ><D>f+TRxkKwhmo9G2OL5JWJOJH5Y2vVM4F32EvsCVTNfvlpcYXzwZCAKb//wgWnwco7B9oyRGv44sDIyLo6KVh9sKc4iERJ5q+ZaTHoSU4TX53/mBiA778rhPXVub22IdBDCJ4VOR4WuUT6tQeXXnPIMw57j3Mroj4auNvYc6kHdyE=</D></RSAKeyValue> --------------------编程问答-------------------- 我这个方法只用到了公钥 私钥在其他方法用的 我就没给出来 --------------------编程问答-------------------- 我自己搞定了 我把公钥和私钥写反了。。。
