在COM中对密文的读写问题，这个贴子100分，如果能解决，我再给您100分。这个很重要！！谢谢!!

[qingwwei]

在一个COM封装得接口中BYTE* pbSignedAndEncryptedBlob为加密的密文
DWORD cbSignedAndEncryptedBlob 为密文长度

我这样将密文写入文件EncryptedMessage.txt
FILE *fp;
fp = fopen( "EncryptedMessage.txt", "w+" );
fwrite ( pbSignedAndEncryptedBlob, cbSignedAndEncryptedBlob, 1, fp );

在另外一个解密接口，我想将密文读入BYTE* pbSignedAndEncryptedBlob，进行解密
FILE *fp;
fp = fopen( "EncryptedMessage.txt", "r+" );
BYTE* pbSignedAndEncryptedBlob = new BYTE[cbSignedAndEncryptedBlob];
fread ( pbSignedAndEncryptedBlob, cbSignedAndEncryptedBlob, 1, fp );
fclose ( fp );

为了验证，我将它再次写入另一个文件EncryptedMessage2.txt
FILE *fp1;
fp1 = fopen( "EncryptedMessage2.txt", "w+" );
fwrite ( pbSignedAndEncryptedBlob, cbSignedAndEncryptedBlob, 1, fp1 );
fclose ( fp1 );

结果

我修改 读的过程
BYTE* pbSignedAndEncryptedBlob = new BYTE[cbSignedAndEncryptedBlob];

请给出详细的步骤，有代码最好，我快疯了，昨天搞了一天，实在不想动了！

[zzyx]

kao,还没有搞定？同情中

[zengruidl]

源码工程发至[e-mail],看看再说。

[Jim3277]

我给你一定在COM中加解密的程序，用DES加密法，你要就给EMAIL给我。

[skybblue]

你在你的fopen函数中，把"w+""r+",改成"wb","rb"试试，我想这样就没有问题了！

那100分什么时候给！哈哈
