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

Dim crypt As New Chilkat.Crypt2

// Any type of file may be hashed.
// There is  no size limitation because the file is consumed
// in streaming mode internally.
Dim filename As String

crypt.EncodingMode = "hex"

// Other possible EncodingMode settings are: 
// "quoted-printable", "base64", "base32", and "url"

Dim hash As String

System.DebugLog("SHA1:")
System.DebugLog(hash)

// Hash using MD2
crypt.HashAlgorithm = "md2"

System.DebugLog(hash)

// Hash using MD5
crypt.HashAlgorithm = "md5"

// Hash using SHA-256

// Hash using HAVAL
// There are two additional properties relevant to HAVAL:
// HavalRounds, and KeyLength.
// HavalRounds can have values of 3, 4, or 5.
// KeyLength can have values of 128, 160, 192, 224, or 256
