It uses S/MIME encryption. Requirements ------------ [](#requirements) - SilverStripe ^5 - SilverStripe Elemental Forms Installation ------------ [](#installation) To start using this module, just add it as a dependency to your project. ``` composer require silverstripeltd/user-configurable-smime-forms ``` License ------- [](#license) See [License](license.md) Documentation ------------- [](#documentation) When configuring user forms within the CMS you can specify whether the submitted form data is emailed to a list of Recipients. This module provides an additional option to encrypt the email. This is specifically useful when you are sending emails to known recipients, and requires the recipient's encryption certificate (.crt file). This module adds an admin section (ModelAdmin) for managing and uploading S/MIME certificates for the purpose of encryption and digital signing of emails. ### Enable Encryption of Emails [](#enable-encryption-of-emails) To enable encryption, go to the **Configuration** tab for your form and check the **Enable S/MIME Encryption** option. With this option set when a form submission is sent to a recipient the system will check for an uploaded encryption certificate for that user. Note: If one does not yet exist the email will be sent unencrypted with a warning (**UNENCRYPTED: CHECK CMS CONFIGURATION**) added to the email subject. [![](./docs/assets/EncryptionOption.png)](./docs/assets/EncryptionOption.png) ### Managing S/MIME Certificates [](#managing-smime-certificates) This module adds an S/MIME Certificates ModelAdmin to the CMS left hand menu for managing encryption and signing certificates and by default it is available to administrators with full access rights. To provide specific CMS groups (e.g., IT administrator users) with the ability to manage these certificates, you can add the `Manage S/MIME certificates` permission to their permissions group in the Security section of the CMS. [![](./docs/assets/CertificatesModelAdmin.png)](./docs/assets/CertificatesModelAdmin.png) ### Adding recipient encryption certificates [](#adding-recipient-encryption-certificates) To add encryption certificates to the CMS: - Log into the CMS as an administrator or user/group with the **Manage S/MIME certificates** permission - From the CMS left hand menu select **S/MIME Certificates** - The default view shows a grid view of uploaded encryption certificates. - Click on **Add Encryption Certificate** - Enter a valid **Email address** - Upload a valid `.crt` file to the **Encryption Certificate** field - Click **Create** [![](./docs/assets/RecipientCertificate.png)](./docs/assets/RecipientCertificate.png) ### Adding sender certificates for digitally signing emails [](#adding-sender-certificates-for-digitally-signing-emails) This module supports digital signing of emails, which provides further assurance for the recipient of where the email comes from. To sign an email you need both the certificate .pem and private key .pem files. To upload these into the CMS: - Log into the CMS as an administrator or user/group with the **Manage S/MIME certificates** permission - From the CMS left hand menu select **S/MIME Certificates** - Select the **Signing Certificates** tab - Click on **Add Signing Certificate** - Enter a valid **Email address** - Upload a valid `.pem` file containing the certificate to the **Signing Certificate** field - Upload a valid `.pem` file containing the private key to the **Signing Key** field - Enter the passphrase for the `.pem` file (this will not be shown and will be stored in an encrypted format) - Click **Create** Maintainers ----------- [](#maintainers) - Andrew Dunn - Paul Jayme Bugtracker ---------- [](#bugtracker) Bugs are tracked in the issues section of this repository.
