解密AES-196-ECB文件，試圖對文件進行加密，但是當它解密

Question

這裏是我的代碼不能恢復文件：

/* DECRYPTION */ 
int i; 
aes_decrypt_ctx ctx[1]; 
//aes_encrypt_ctx ctx[1]; 
unsigned char iv[16]; 
unsigned char inBuffer[200], outBuffer[200]; 
FILE *inFile1=fopen("C:/sth.txt.aes", "rb"); /* used to read IV ONLY */ 
FILE *inFile2=fopen("C:/sth.txt.aes", "rb"); /* used to read the whole file, included IV */ 
FILE *outFile=fopen("C:/sth.txt", "wb"); 
if (inFile1 != NULL) { 
    lbl_status->Text+="\r\nFinding IV(first 16 byte) of the file..."; 
    /* read initialization vector from file */ 
    if(fread(iv, 1, 16, inFile1) >= 16) { 
    lbl_status->Text+="\r\nFound IV(first 16 byte) in the file..."; 
    fclose(inFile1); 
    aes_decrypt_key192((unsigned char*)MStringToCCS(decryptsecret), ctx); 

    // Start decrypting 
    lbl_status->Text+="\r\nStart decrypting..."; 
    while((i=fread(inBuffer, 1, sizeof(inBuffer), inFile2)) > 0) { 
     aes_ecb_decrypt(inBuffer, outBuffer, i, ctx); 
     fwrite(outBuffer, 1, i, outFile); 
    } 
    fclose(inFile2); 
    fclose(outFile); 
    }else{ 
    /* error: file doesn't even contain an initialisation vector */ 
    lbl_status->Text+="\r\nError: IV(first 16 byte) not found."; 
    MessageBox::Show("Could not find the IV.", "Error", MessageBoxButtons::OK, MessageBoxIcon::Error); 
    fclose(inFile1); 
    fclose(inFile2); 
    fclose(outFile); 
    } 
}else{ 
    lbl_status->Text+="\r\nError: Could not open the file."; 
    MessageBox::Show("Error for opening the file.", "Error", MessageBoxButtons::OK, MessageBoxIcon::Error); 
    fclose(inFile1); 
    fclose(inFile2); 
    fclose(outFile); 
} 

首先，我創建了一個AES-使用openssl加密文件： openssl enc -e -aes-192-ecb -in C:/sth.txt -out C:/sth.txt.aes 我試過我的程序，但輸出與原始文件不同。

任何解決方案？

我建議你在C++中使用便攜庫，例如Crypto++或Botan用於加密。這些圖書館受到好評，並有良好的社區支持。
