json 形式のユーザー データをエンコードする C# コード
// Encode the data into a JSON object
JavaScriptSerializer s = new JavaScriptSerializer();
string json_data = s.Serialize(user_data);
string site_key = "84129";
string api_key = "0d2c15da-b36f-4a9c-8f44-93eb95811e2e-05e1fb36-54aa-44fc-888e-45d2669c3013";
byte[] bIV = { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };
//Using byte arrays now instead of strings
byte[] encrypted = null;
byte[] data = Encoding.ASCII.GetBytes(json_data);
//Use the AesManaged object to do the encryption
using (AesManaged aesAlg = new AesManaged())
{
aesAlg.IV = bIV;
aesAlg.KeySize = 16 * 8;
// Create the 16-byte salted hash
SHA1 sha1 = SHA1.Create();
byte[] saltedHash = sha1.ComputeHash(Encoding.ASCII.GetBytes(api_key + site_key), 0, (api_key + site_key).Length);
Array.Resize(ref saltedHash, 16);
aesAlg.Key = saltedHash;
// Encrypt using the AES Managed object
ICryptoTransform encryptor = aesAlg.CreateEncryptor();
using (MemoryStream msEncrypt = new MemoryStream())
{
using (CryptoStream csEncrypt = new CryptoStream(msEncrypt, encryptor, CryptoStreamMode.Write))
{
csEncrypt.Write(data, 0, data.Length);
csEncrypt.FlushFinalBlock();
}
encrypted = msEncrypt.ToArray();
}
}
// the Base64-encoded encrypted data
string encodedData= Convert.ToBase64String(encrypted, Base64FormattingOptions.None)
.TrimEnd("=".ToCharArray()) // Remove trailing equal (=) characters
.Replace("+", "-") // Change any plus (+) characters to dashes (-)
.Replace("/", "_"); // Change any slashes (/) characters to underscores (_)
注:json_data文字列は次のようになります..
{"email":"chandresh@domainname.com","name":"chandresh","expires":"2013-07-05T11:47:32"}
上記の C# 作業コードと同等の CryptoJS コードを作成しようとしました。
どういうわけか、行われた暗号化/エンコードは有効なencodedDataではありません。助けてください
