(Lianja) Decrypt2

Demonstrates how to decrypt MIME using a certificate and private key where the certificate and its corresponding private key are stored in separate files -- a .cer for the certificate, and a .pem for the private key.

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

loMime = createobject("CkMime")

// Load the certificate from a .cer file.
loCert = createobject("CkCert")

if (llSuccess = .F.) then
    ? loCert.LastErrorText
    release loMime
    release loCert

endif

// Load the private key from an encrypted PEM file.
// (A private key can be loaded from other file formats also..)
