algorithms

how would i take text from a textbox, put it through a agrorythem and then write the agrorythem result to the registry?

Are you talking about angry music, or do you mean an algorithm? An algorithm is just a method of performing some calculation, so you need to implement it yourself in code. That means you would pass the Text property of the TextBox to a function you have written that implements the algorithm and then write the result to the registry. I KNOW you know how to write to the registry, right?

lol, my bad, algrorithm, i'm using it to encrypt my password, i think i got it but can you give me a example, and yes i do know how to write to the registry lol.

Here is an example from freevbcode.com,

VB Code:

Pubilc Function WriteToRegistry(ByVal _
    ParentKeyHive As RegistryHive, _
    ByVal SubKeyName As String, _
    ByVal ValueName As String, _
    ByVal Value As Object) As Boolean
 
'DEMO USAGE
'Dim bAns As Boolean
'bAns = WriteToRegistry(RegistryHive.LocalMachine, "SOFTWARE\MyCompany\MyProgram\", "ProgramHasRunBefore", "Y")
'Debug.WriteLine("Registry Write Successful: " & bAns)
 
        Dim objSubKey As RegistryKey
        Dim sException As String
        Dim objParentKey As RegistryKey
        Dim bAns As Boolean
 
 
        Try
 
            Select Case ParentKeyHive
                Case RegistryHive.ClassesRoot
                    objParentKey = Registry.ClassesRoot
                Case RegistryHive.CurrentConfig
                    objParentKey = Registry.CurrentConfig
                Case RegistryHive.CurrentUser
                    objParentKey = Registry.CurrentUser
                Case RegistryHive.DynData
                    objParentKey = Registry.DynData
                Case RegistryHive.LocalMachine
                    objParentKey = Registry.LocalMachine
                Case RegistryHive.PerformanceData
                    objParentKey = Registry.PerformanceData
                Case RegistryHive.Users
                    objParentKey = Registry.Users
 
            End Select
 
 
            'Open 
            objSubKey = objParentKey.OpenSubKey(SubKeyName, True)
            'create if doesn't exist
            If objSubKey Is Nothing Then
                objSubKey = objParentKey.CreateSubKey(SubKeyName)
            End If
 
 
            objSubKey.SetValue(ValueName, Value)
            bAns = True
        Catch ex As Exception
            bAns = False
 
        End Try
 
        Return True
 
    End Function

"Agro" is an Australian colloquialism, short for "aggravation" or "aggravated", and "rythem" is almost "rhythm", so together they could be the new term for some aussie heavy metal. (Sorry metal fans but some of it sounds angry to me)

cdubb07, which algorithm are you using to encrypt your passwords? .NET has in-built support for MD5 and SHA1, so a help/MSDN search for either of those terms should give you some results. Note that these are hasing algorithms so the encryption is one-way, i.e. the hash value can never be used to re-create the original password. They are generally used to encrypt a password when it is created, then on subsequent logins the password provided is hashed using the same algorithm and compared to the stored value. That way it is safe to store the hashed password in an unsecure location, like a text file.

how would i go about enabling md5?

VB Code:

Dim unencryptedPassword As String 'Put actual password here.
Dim unencryptedBytes As Byte() = System.Text.Encoding.Unicode.GetBytes(unencryptedPassword)
Dim md5Encrypter As New System.Security.Cryptography.MD5CryptoServiceProvider
Dim encryptedBytes As Byte() = md5Encrypter.ComputeHash(unencryptedBytes)
Dim encryptedPassword As String = System.Text.Encoding.Unicode.GetString(encryptedBytes)

Note that I've never done that before myself. I just looked it up in the help and used a bit of deduction.
