Requirements
------------

[](#requirements)

PHP 8.1 or newer, and [zbateson/mail-mime-parser](https://github.com/zbateson/mail-mime-parser) 4.x.

Description
-----------

[](#description)

This is the base package for mail-mime-parser's cryptographic plugin system. It provides:

- `IMimeCrypt` -- interface for encryption/decryption/signing/verification implementations
- `AbstractMimeCrypt` -- base class implementing `IMimeCrypt` with stream handling
- `EncryptedMessage` / `EncryptedMimePart` -- message/part classes that transparently expose decrypted content via `getStream()`, with `getEncryptedStream()` for accessing the original encrypted data

On its own, this package doesn't perform any cryptographic operations. Install an implementation package:

- [zbateson/mmp-crypt-smime](https://github.com/zbateson/mmp-crypt-smime) -- S/MIME via PHP's OpenSSL extension
- [zbateson/mmp-crypt-gpg](https://github.com/zbateson/mmp-crypt-gpg) -- PGP/MIME via the PECL gnupg extension

Usage
-----

[](#usage)

```
use ZBateson\MailMimeParser\Message;

// Parsing an encrypted message automatically uses the registered
// IMimeCrypt implementation to decrypt it.
$message = Message::from($rawEmail, false);

// If the message was encrypted, it will be an EncryptedMessage instance.
// getStream() / getTextContent() / etc. return decrypted content by default.
echo $message->getTextContent();

// Access the original encrypted stream if needed
if ($message instanceof \ZBateson\MmpCrypt\EncryptedMessage) {
    $encryptedStream = $message->getEncryptedStream();
}
```
