(PHP ActiveX) Send a Signed Email using RSASSA-PSS with SHA256Demonstrates how to sign and send an email using the RSASSA-PSS signing algorithm with the SHA256 hash algorithm. Note: This example requires Chilkat v9.5.0.67 or greater.
<?php // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // Get a digital certificate with private key from a .pfx // (Chilkat has many different ways to provide a cert + private key for siging. // Using a PFX is just one possible option.) // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Pfx') $pfx = new COM("Chilkat.Pfx"); $success = $pfx->LoadPfxFile('qa_data/rsassa-pss/privatekey.pfx','PFX_PASSWORD'); if ($success != 1) { print $pfx->LastErrorText .
