If you want to decrypt a received email, keep in mind that you need the full encrypted message including the mime header.

<?php

// Get the full message
$encrypted imap_fetchmime($stream$msg_number"1"FT_UID);
$encrypted .= imap_fetchbody($stream$msg_number"1"FT_UID);

// Write the needed temporary files
$infile tempnam("""enc");
file_put_contents($infile$encrypted); 
$outfile tempnam("""dec");

// The certification stuff
$public file_get_contents("/path/to/your/cert.pem");
$private = array(file_get_contents("/path/to/your/cert.pem"), "password");

// Ready? Go!
if(openssl_pkcs7_decrypt($infile$outfile$public$private))
{
   
// Decryption successful
   
echo file_get_contents($outfile);
}
else
{
   
// Decryption failed
   
echo "Oh oh! Decryption failed!";
}

// Remove the temp files
@unlink($infile);
@
unlink($outfile);
