Find Certificate for Email Encryption

Demonstrates finding the recipient's certificate in the Windows certificate store and using it to send encrypted email. CkPython

import sys
import chilkat

success = False

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

mailman = chilkat.CkMailMan()

# Set the SMTP server.
mailman.put_SmtpHost("smtp.example.com")

# Create a new email object
email = chilkat.CkEmail()

email.put_Subject("This email is encrypted")
email.put_Body("This is a digitally encrypted mail")
email.put_From("Joe <joe@example.com>")
# Emails are encrypted using the recipient's certificate.
recipientEmailAddr = "jane@example2.com"
email.AddTo("Jane",recipientEmailAddr)

# Indicate that the email is to be sent encrypted.
email.put_SendEncrypted(True)

# This example demonstrates finding the email encryption certificate
# on a Windows system where the certificate is stored in the Windows 
# certificate store.

cert = chilkat.CkCert()
# The recipient's certificate is used to encrypt.
# (Because the recipient is the only one in possession of the private key to decrypt.)
success = cert.LoadByEmailAddress(recipientEmailAddr)
if (success != True):
    print(cert.lastErrorText())
    sys.exit()

# Specify the certificate to be used for encryption.
success = email.SetEncryptCert(cert)

success = mailman.SendEmail(email)
if (success != True):
    print(mailman.lastErrorText())

    print("Encrypted Mail Sent!")
