Procedure Test
    Handle hoCrypt
    String s
    String sHash

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

    Get Create (RefClass(cComChilkatCrypt2)) To hoCrypt
    If (Not(IsComObjectCreated(hoCrypt))) Begin
        Send CreateComObject of hoCrypt
    End

    Move "The quick brown fox jumps over the lazy dog" To s

    Set ComHashAlgorithm Of hoCrypt To "sha1"
    Set ComEncodingMode Of hoCrypt To "hex"

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

    Get ComHashStringENC Of hoCrypt s To sHash
    Showln "SHA1: " sHash

    // Hash using MD2
    Set ComHashAlgorithm Of hoCrypt To "md2"
    Get ComHashStringENC Of hoCrypt s To sHash
    Showln "MD2: " sHash

    // Hash using MD5
    Set ComHashAlgorithm Of hoCrypt To "md5"
    Get ComHashStringENC Of hoCrypt s To sHash
    Showln "MD5: " sHash

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

    // Hash using SHA-256
    Set ComHashAlgorithm Of hoCrypt To "sha256"
    Get ComHashStringENC Of hoCrypt s To sHash
    Showln "SHA256: " sHash

    // Hash using SHA-384
    Set ComHashAlgorithm Of hoCrypt To "sha384"
    Get ComHashStringENC Of hoCrypt s To sHash
    Showln "SHA384: " sHash

    // Hash using SHA-512
    Set ComHashAlgorithm Of hoCrypt To "sha512"
    Get ComHashStringENC Of hoCrypt s To sHash
    Showln "SHA512: " sHash

    // 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
    Set ComHashAlgorithm Of hoCrypt To "haval"
    Set ComHavalRounds Of hoCrypt To 5
    Set ComKeyLength Of hoCrypt To 256
    Get ComHashStringENC Of hoCrypt s To sHash
    Showln "Haval: " sHash
