Decrypt S/MIME using a PFX File

See more MIME Examples

Loads a CMS/PKCS #7 encrypted S/MIME message and decrypts it back to the original MIME content.

DecryptUsingPfxFile decrypts using the certificates and private keys contained in a PFX/P12 file, identified by path and password.

The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

import sys
import chilkat2

success = False

mime = chilkat2.Mime()
success = mime.LoadMimeFile("qa_data/encrypted.eml")
if (success == False):
    print(mime.LastErrorText)
    sys.exit()

# Decrypt using the certificates and private keys in a PFX/P12 file.  The 1st argument is the PFX
# path and the 2nd is its password (which should come from a secure source).
pfxPassword = "myPfxPassword"
success = mime.DecryptUsingPfxFile("qa_data/recipient.pfx",pfxPassword)
if (success == False):
    print(mime.LastErrorText)
    sys.exit()

body = mime.GetBodyDecoded()
if (mime.LastMethodSuccess == False):
    print(mime.LastErrorText)
    sys.exit()

print(body)
