PKCS7 Decrypt Using .pfx or .p12 File

See more MIME Examples

Demonstrates how to decrypt MIME using a specifc PFX file (.pfx or .p12) for the source of certificate(s) and private key(s). Lua

local chilkat = require("chilkat")

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

local mime = chilkat.Mime.new()

-- Load the MIME
local success = mime:load_mime_file("encrypted.mim")
if not success then
    print(mime.last_error_text)
    return
end

-- Decrypt using a specific PFX file:
local pfxPassword = "myPassword"
success = mime:decrypt_using_pfx_file("c:/myPfxFiles/myCertAndPrivateKey.pfx", pfxPassword)
if not success then
    print(mime.last_error_text)
    return
end

-- Display the decrypted MIME:
print(mime:get_mime())

-- Note: The MIME to be decrypted should look something like this
-- when viewed in a text editor:
-- (Note that the Content-Type is application/x-pkcs7-mime)

-- Content-Disposition: attachment; filename="smime.p7m";
-- Content-Transfer-Encoding: base64
-- Content-Type: application/x-pkcs7-mime;
