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

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Crypt2")
set crypt = Server.CreateObject("Chilkat.Crypt2")

s = "The quick brown fox jumps over the lazy dog"

crypt.HashAlgorithm = "sha1"

' Other possible EncodingMode settings are: 
' "quoted-printable", "base64","url", and many more..

hash = crypt.HashStringENC(s)
Response.Write "<pre>" & Server.HTMLEncode( "SHA1: " & hash) & "</pre>"

' Hash using MD2
crypt.HashAlgorithm = "md2"

' Hash using MD5

Response.Write "<pre>" & Server.HTMLEncode( "MD5: " & hash) & "</pre>"

' Note: SHA-2 is a set of cryptographic hash functions (SHA-224, SHA-256, SHA-384, SHA-512)

' Hash using SHA-256
crypt.HashAlgorithm = "sha256"
hash = crypt.HashStringENC(s)

' Hash using SHA-384

' Hash using SHA-512
crypt.HashAlgorithm = "sha512"
hash = crypt.HashStringENC(s)
Response.Write "<pre>" & Server.HTMLEncode( "SHA512: " & hash) & "</pre>"

' 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
crypt.HashAlgorithm = "haval"
crypt.HavalRounds = 5
crypt.KeyLength = 256
