Platform to track Software development progress.
Developed using:
- Design Patterns: Repository patern, Unit of Work design pattern.
- Authorization with Password Encryption.
- Entity Framework
- MS SQL SERVER Database
- Unit-Testing
Design Patterns: Repository patern, Unit of Work design pattern, MVVM (Model-View-ViewModel) For Windows Form Applications.
Implementation of Repository patern: here
public interface IRepository<TEntity> where TEntity : class
{
TEntity Get(string id);
IEnumerable<TEntity> GetAll();
IEnumerable<TEntity> Find(Expression<Func<TEntity, bool>> predicate);
void Add(TEntity entity);
void AddRange(List<TEntity> entities);
void Remove(TEntity entity);
void RemoveRange(List<TEntity> entities);
bool CheckExistance(TEntity entity);
}Implementation of Unit of Work here
public interface IUnityOfWork : IDisposable
{
IProjectRepository Project { get; }
ITaskRepository Task { get; }
IDocumentRepository Document { get; }
ITeamRepository Team { get; }
IClientRepository Client { get; }
IDeveloperRepository Developer { get; }
ISeniorRepository Senior { get; }
IAdministratorRepository Administrator { get; }
int Complete();
}For the implementation used helper class encrypt: here
internal static class Encrypt
{
private const string initVector = "pemgail9uzpgz188";
private const int keysize = 256;
public static string EncryptString(string plainText, string passPhrase)
{
byte[] initVectorBytes = Encoding.UTF8.GetBytes(initVector);
byte[] plainTextBytes = Encoding.UTF8.GetBytes(plainText);
PasswordDeriveBytes password = new PasswordDeriveBytes(passPhrase, null);
byte[] keyBytes = password.GetBytes(keysize / 8);
RijndaelManaged symmetricKey = new RijndaelManaged();
symmetricKey.Mode = CipherMode.CBC;
ICryptoTransform encryptor = symmetricKey.CreateEncryptor(keyBytes, initVectorBytes);
MemoryStream memoryStream = new MemoryStream();
CryptoStream cryptoStream = new CryptoStream(memoryStream, encryptor, CryptoStreamMode.Write);
cryptoStream.Write(plainTextBytes, 0, plainTextBytes.Length);
cryptoStream.FlushFinalBlock();
byte[] cipherTextBytes = memoryStream.ToArray();
memoryStream.Close();
cryptoStream.Close();
return Convert.ToBase64String(cipherTextBytes);
}
public static string DecryptString(string cipherText, string passPhrase)
{
byte[] initVectorBytes = Encoding.UTF8.GetBytes(initVector);
byte[] cipherTextBytes = Convert.FromBase64String(cipherText);
PasswordDeriveBytes password = new PasswordDeriveBytes(passPhrase, null);
byte[] keyBytes = password.GetBytes(keysize / 8);
RijndaelManaged symmetricKey = new RijndaelManaged();
symmetricKey.Mode = CipherMode.CBC;
ICryptoTransform decryptor = symmetricKey.CreateDecryptor(keyBytes, initVectorBytes);
MemoryStream memoryStream = new MemoryStream(cipherTextBytes);
CryptoStream cryptoStream = new CryptoStream(memoryStream, decryptor, CryptoStreamMode.Read);
byte[] plainTextBytes = new byte[cipherTextBytes.Length];
int decryptedByteCount = cryptoStream.Read(plainTextBytes, 0, plainTextBytes.Length);
memoryStream.Close();
cryptoStream.Close();
return Encoding.UTF8.GetString(plainTextBytes, 0, decryptedByteCount);
}Logic is devided in three main parts: model view view-model :here
The interaction with the Database was done all through Entity Framework: here
