Hi,
Here is a piece of code coming from a project I'm currently working on.
It shows how to generate a hash( md5 or sha-1) and change the password of
the user on the google system.
It's a C# code, you should be able to easily port it to the language of your
choice.
/// <summary>
/// Login in Google System
/// </summary>
internal void Login()
{
service = new AppsService(_Domain, _AdministratorEmail,
_AdministratorPassword);
if (service == null)
throw new Exception("Login Failed");
}
/// <summary>
/// Set ¨Password Hashing function
/// </summary>
/// <param name="hashFunction"></param>
internal void SetHashFunction(string hashFunction)
{
_HashFunction = hashFunction.ToLower();
}
/// <summary>
/// Change Password of user account
/// </summary>
/// <param name="userName"></param>
/// <param name="password"></param>
internal void SetPassword(string userName,string password)
{
//Search the user
UserEntry entry = service.RetrieveUser(userName);
//change the pasword
entry.Login.Password = Hash(password);
entry.Login.HashFunctionName = _HashFunction;
//save modification
entry.Update();
}
private string Hash(string password)
{
if (string.Compare(_HashFunction, "md5") == 0)
{
return CalculateMD5Hash(password);
}
if (string.Compare(_HashFunction, "sha1") == 0)
{
return CalculateSHA1Hash(password);
}
return string.Empty;
}
/// <summary>
/// Hash password using MD5
/// </summary>
/// <param name="input"></param>
/// <returns></returns>
private string CalculateMD5Hash(string password)
{
MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();
byte[] bs = System.Text.Encoding.UTF8.GetBytes(password);
bs = md5.ComputeHash(bs);
System.Text.StringBuilder s = new System.Text.StringBuilder();
foreach (byte b in bs)
{
s.Append(b.ToString("x2").ToLower());
}
return s.ToString();
}
/// <summary>
/// Hash password using MD5
/// </summary>
/// <param name="input"></param>
/// <returns></returns>
private string CalculateSHA1Hash(string password)
{
SHA1CryptoServiceProvider sha1 = new
SHA1CryptoServiceProvider();
byte[] bs = System.Text.Encoding.UTF8.GetBytes(password);
bs = sha1.ComputeHash(bs);
System.Text.StringBuilder s = new System.Text.StringBuilder();
foreach (byte b in bs)
{
s.Append(b.ToString("x2").ToLower());
}
return s.ToString();
}
