我有一个来自第三方的加密示例，我需要与...
集成我应该向他们发送加密消息，他们确实在其结束时解密并执行所需的操作。
他们为我提供了一个示例，这就是他们期望将字符串加密的方式。
echo -n ['字符串到加密'] |OpenSSL ENC -AES -128 -CBC -A -A -NOLASALT -K [HEX中的EncryptionKey]
我给予的Sandbox EncryptionKey hex是313233333333373839
当前，我无法按照以上指定的密钥和iv使用。
然后，我只是用0填充键以匹配32个字节，然后将IV截断以匹配16字节。
然后我能够至少运行代码，但是我的C＃代码中的加密字符串无法在OpenSSL上解密。
以下是我的代码。
public static string EncryptString(string plainText, string password)
{
byte[] key, iv;
//converting key to hex
byte[] ba = Encoding.ASCII.GetBytes("0123456789abcdef");
string encryptionKeyHex = BitConverter.ToString(ba);
encryptionKeyHex = encryptionKeyHex.Replace("-", "");
// Padding key hex with zeros to match the size that .Net algo expects
if (encryptionKeyHex.Length < 32)
{
while (encryptionKeyHex.Length < 32)
{
encryptionKeyHex += "0";
}
}
var keyBytes = Encoding.ASCII.GetBytes(encryptionKeyHex);
var ivBytes = Encoding.ASCII.GetBytes("3030303030303030"); // truncated the original IV specified in the question description to match the size.
iv = ivBytes;
key = keyBytes;
var amAes = new AesManaged();
amAes.Mode = CipherMode.CBC;
amAes.Padding = PaddingMode.PKCS7;
amAes.KeySize = 128;
amAes.BlockSize = 128;
amAes.Key = key;
amAes.IV = iv;
var icTransformer = amAes.CreateEncryptor();
var msTemp = new MemoryStream();
var csEncrypt = new CryptoStream(msTemp, icTransformer, CryptoStreamMode.Write);
var sw = new StreamWriter(csEncrypt);
sw.Write(plainText);
sw.Close();
sw.Dispose();
csEncrypt.Clear();
csEncrypt.Dispose();
byte[] bResult = msTemp.ToArray();
//var sha = new SHA1CryptoServiceProvider();
//var result = sha.ComputeHash(bResult);
string sResult = Convert.ToBase64String(bResult);
sResult = HttpUtility.UrlEncode(sResult);
if (System.Diagnostics.Debugger.IsAttached)
{
string debugDetails = "";
debugDetails += "==> INPUT : " + plainText + Environment.NewLine;
debugDetails += "==> SECRET : " + password + Environment.NewLine;
//debugDetails += "==> SALT : " + Program.ByteArrayToHexString(salt) + Environment.NewLine;
debugDetails += "==> KEY : " + Encoding.ASCII.GetString(amAes.Key) + " (" + amAes.KeySize.ToString() + ")" + Environment.NewLine;
debugDetails += "==> IV : " + Encoding.ASCII.GetString(amAes.IV) + Environment.NewLine;
debugDetails += "==> ENCRYPTED : " + sResult;
Console.WriteLine(debugDetails);
}
return sResult;
}
输出：
==>输入：{" filter.accession_number.quals"：" 0987654321"}
==>秘密：==>键：3031323333333373738390000000000000000000000000000000000000000000000000000000000000000000000000000000000000000来入

已经注意到，在Windows盒上加密时，我们获得了与Linux盒上使用相同方法的不同结果。
在Linux Box上使用OpenSSL，我们得到..
命令：echo -n'{" filter.accession_number.quals"：" 0987654321"}'|
结果：mtausb6rykxyf9/rebfq9m1xwr 6q58ffsjptxdnwgs6z3jz3jz8ru 7ysnkuy2p3 ax
加密的字符串正常工作..我能够成功解密它。
在Windows Box上向OpenSSL发出相同的命令时，给了我们..
命令：echo -n'{" filter.accession_number.quals"：" 0987654321"}'|
结果：DB9829Q6QX6CPWLKE RS6ZQRJJQAGZ9XK7FBZTAGQSKCCSKCHPCR7EQU7EQUZ3YOJPLC S6YVW4JXQTZOK4JXQTZOOK43F16GW7SPW ==
此字符串不起作用...
您只是忘记解码十六进制；Encoding.ASCII.GetBytes仅获取键和IV的ASCII表示。
在此处检查答案以正确转换为字节（即用StringToByteArray替换Encoding.ASCII.GetBytes）。
这是遇到类似问题的任何人的工作代码样本...@Maarten Bodewes您确实指出了正确的方向，只需要重新安排代码才能使其正常工作。谢谢:)
