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

Dim crypt As New Chilkat.Crypt2

// Set the name of the hash algorithm.
// Other choices include "sha1", "sha256", "sha384", "sha512", "md2", "md5", and "haval". 
crypt.HashAlgorithm = "md5"

// EncodingMode specifies the encoding of the hash output.
// It may be "hex", "url", "base64", or "quoted-printable".
crypt.EncodingMode = "hex"

// Files of any type may be hashed -- it doesn't matter
// if the file is binary or text...
Dim hashStr As String
hashStr = crypt.HashFileENC("/temp/something.dat")
If (crypt.LastMethodSuccess <> True) Then
    System.DebugLog(crypt.LastErrorText)
    Return
End If

System.DebugLog(hashStr)
