DataProtect utils to encrypt and/or decrypt data again and again

[thrzn41]

ProtectedString can be used to encrypt and/or decrypt a string, but it has each encryption/decryption instance.
This means an instance of ProtectedString cannot be reused to encrypt another string.

To encrypt and/or decrypt data again and again, DataProtect class will be implemented.

Code snipped(may be changed):

using(var ldp = LocalDataProtect.Create())
{
    var encrypted = ldp.Encrypt(data);
}

using(var pdp = PBEDataProtect.Create(password))
{
    var encrypted = pdb.Encrypt(data);
}
