Calculate MD5 Hash of File (or SHA1, SHA256, and other hash algorithms)

See more Encryption Examples

Demonstrates how to calculate a hash for a file's contents. PowerBuilder

integer li_rc
oleobject loo_Crypt
string ls_HashStr

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

loo_Crypt = create oleobject
li_rc = loo_Crypt.ConnectToNewObject("Chilkat.Crypt2")
if li_rc < 0 then
    destroy loo_Crypt
    MessageBox("Error","Connecting to COM object failed")
    return
end if

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

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

// Files of any type may be hashed -- it doesn't matter
// if the file is binary or text...

if loo_Crypt.LastMethodSuccess <> 1 then
    Write-Debug loo_Crypt.LastErrorText

Write-Debug ls_HashStr
