' This example requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

Dim crypt As New Chilkat.Crypt2

' Set the encryption algorithm to ARC4:	
crypt.CryptAlgorithm = "arc4"

' We want the encrypted output to be a hex-encoded string.
crypt.EncodingMode = "hex"

Dim key As String = "000102030405060708090A0B0C0D0E0F"
Dim data As String = "12345678"

' Key length is 128 bits in this example.
crypt.KeyLength = 128
crypt.SetEncodedKey(key,"hex")

' Generate 16 "random" 8-byte blocks, encoded as hex strings.
' This example will generate the identical output each time
' it is run.
Dim cipherHex As String
Dim i As Integer
For i = 0 To 15
    cipherHex = crypt.EncryptStringENC(data)
    Debug.WriteLine(data)
    Debug.WriteLine(cipherHex)
    data = cipherHex
