使用c#加密数据并使用openssl api对其进行解密,为什么解密数据末

86afaecb-c211-4d55-8e90-2b715d6d64b9

并将加密数据写入文件.然后,我使用openssl api从文件中读取加密数据并解密.但是,我得到的输出为：

86afaecb-c211-4d55-8e90-2b715d6d64b9oeheBjQ8fo1AmDnor1D3BLuPyq9wJBAOV+M/WVNYzYr

似乎原始字符串末尾有一些无用的填充.为什么会这样？以及如何解决问题？

一些代码段如下所示：

// Encrypt
{
    string plainData = “86afaecb-c211-4d55-8e90-2b715d6d64b9”;
    RSACryptoServiceProvider rsa = new RSACryptoServiceProvider();
    rsa.ImportParameters(paraPub);
    byte[] testData = Encoding.UTF8.GetBytes(plainData);
    byte[] encryptedData = rsa.Encrypt(testData,true);
    FileStream pFileStream = null;
    string fileName = "encryptedData.dat";
    pFileStream = new FileStream(fileName,FileMode.OpenOrCreate);
    pFileStream.Write(encryptedData,encryptedData.Length);
    ...
}

// Decrypt
{
    char *encrypt = malloc(RSA_size(privateKey));
    FILE *out = fopen("encryptedData.dat","r");
    int encrypt_len = fread(encrypt,sizeof(*encrypt),RSA_size(privateKey),out);
    fclose(out);

    decrypt = malloc(encrypt_len);
    if(RSA_private_decrypt(encrypt_len,(unsigned char*)encrypt,(unsigned char*)decrypt,privateKey,RSA_PKCS1_OAEP_PADDING) == -1) {
        // error handle
    }

    printf("Decrypted message: %sn",decrypt);
}
