PKCS7 Decrypt Using .pfx or .p12 File

See more MIME Examples

Demonstrates how to decrypt MIME using a specifc PFX file (.pfx or .p12) for the source of certificate(s) and private key(s). Ruby

require 'chilkat'

success = false

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

mime = Chilkat::CkMime.new()

# Load the MIME
success = mime.LoadMimeFile("encrypted.mim")
if (success == false)
    print mime.lastErrorText() + "\n";
    exit
end

# Decrypt using a specific PFX file:
pfxPassword = "myPassword"
success = mime.DecryptUsingPfxFile("c:/myPfxFiles/myCertAndPrivateKey.pfx",pfxPassword)
if (success == false)
    print mime.lastErrorText() + "\n";
    exit
end

# Display the decrypted MIME:
print mime.getMime() + "\n";

# Note: The MIME to be decrypted should look something like this
# when viewed in a text editor:
# (Note that the Content-Type is application/x-pkcs7-mime)

# Content-Disposition: attachment; filename="smime.p7m"
# Content-Transfer-Encoding: base64
# Content-Type: application/x-pkcs7-mime;
#  name="smime.p7m"
