    how to encrypt picture files using visual basic so that only certain people who know the password can see the picture

    You can use a simple random XOR shift to do the 'encrypting'... as you probably know XOR of XOR gives original, so you can use the same for encoding/decoding provided the shift key is right. If you supply the file (binary) to this function, then it'll return encoded with the given key.
    If you pass the encoded file, it'll return the original file.


    [courier new]
    Public Function EncodeDecode(Data As String, Key As Long) As String
    On Error Resume Next


    Dim I As Long, X As Single
    Dim CharNum As Integer, RandInteger As Integer
    Dim SingleChar As String * 1
    Dim ReturnData As String


    X = Rnd(-Key)


    For I = 1 To Len(Data)
     CharNum = Asc(Mid$(Data, I, 1))
     RandInteger = Int(256 * Rnd)
     CharNum = CharNum Xor RandInteger
     
     SingleChar = Chr(CharNum)
     ReturnData = ReturnData & SingleChar
    Next I


    EncodeDecode = ReturnData
    End Function
    [/courier new]


    But how do you make a key out of password ? Convert it to a number that vastly varies according to the password...


    [courier new]
    Public Function ConvertPassKey(Key as String) As Long
    Dim I As Integer, Num As Long


    Key = LCase(Key)
    Num = 1
    For I = 1 To Len(Key)
    Num = Num + (I * Asc(Mid(Key, I, 1)))
    Next I


    ConvertPassKey = Num
    End Function
    [/courier new]


    Be VERY, VERY WARY  of the data you pass to the function. A slight shifting of even a single character will ruin the entire decoding process, and you'll get junk data!!!


    I suggest you do multiple "parity" checks before actually give it up for decoding....


    Also, encoding/decoding takes some time... that's why i prefer my tried and tested method "mangle da header!"
    Enjoy !
