(PHP ActiveX) Extract PKCS7 from MIME and Decrypt
Extracts the base64-encoded PKCS7 body of a MIME message to a file, and then decrypts using Chilkat Crypt2.
<?php
// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
$mime = new COM("Chilkat_9_5_0.Mime");
$success = $mime->LoadMimeFile('c:/aaworkarea/EmailInBytes.txt');
if ($success != 1) {
print $mime->LastErrorText . "\n";
exit;
}
$success = $mime->SaveBody('c:/aaworkarea/smime.p7m');
if ($success != 1) {
print $mime->LastErrorText . "\n";
exit;
}
$crypt = new COM("Chilkat_9_5_0.Crypt2");
$success = $crypt->AddPfxSourceFile('c:/aaworkarea/my.pfx','pfxPassword');
if ($success == 0) {
print $crypt->LastErrorText . "\n";
exit;
}
// Indicate the public-key (PKCS7) encryption/decryption should be used:
$crypt->CryptAlgorithm = 'pki';
$inPath = 'c:/aaworkarea/smime.p7m';
$outPath = 'c:/aaworkarea/decrypted.dat';
$success = $crypt->CkDecryptFile($inPath,$outPath);
if ($success == 0) {
print $crypt->LastErrorText . "\n";
exit;
}
print 'Success.' . "\n";
