unable to decrypt emails due to suspected formatting issues

    I’m hoping @meitar or someone can help sort out an issue I’ve been experiencing that seems to have gotten worse over time regarding formatting of encrypted emails sent using this plugin. It seems the messages are encrypted & signed (with the signature encapsulated within the encrypted message payload) inline vs. as MIME attachments. I believe this is leading to issues where the formatting is either off or gets mangled in transit. The result is clients have difficulty parsing the message and either fail to decrypt the message or if they manage to decrypt the message it shows up as blank text and is flagged as “partly encrypted” & “partly signed”. The latter seems to happen exclusively with in the case of GPGTools+GPGMail+Mail.app on macOS, other clients simply show the encrypted payload and are unable or unwilling to decrypt it automatically.

    I have managed to copy & paste the encrypted message from the raw content and then re-format it to the point of being able to decrypt it manually on the command line, but this solution does not work for non-technical users. I’m hoping @meitar or someone can help sort out what is happening here and suggestion a way to address it. Thanks in advance.

    EDIT: to clarify this “seems to have gotten worse over time” refers to the fact that I used to be able to decrypt these messages in past versions of macOS/Mail.app/GPGTools+GPGMail and they would still get flagged as “partly encrypted” & “partly signed”, but with the latest versions of GPGTools+GPGMail on macOS Monterey (12.6.1) I now get a blank message with those same flagged encryption & signature details.

    MIME support for this was requested years ago but I never found the time or other resources to work on its implementation. You have three options: implement MIME support in the plugin, fix inline support in your client, or use a different client. That’s really all there is to it. Shrug?

    Unfortunately, I’m seeing problems in various clients so I don’t think I can find a solution through 2/3 of those options. Is there a way I can help get you the time or other resources to implement MIME support in the plugin? It would also be ideal if it could be tested through the current version of wordpress since a lot has changed between 4.4 & 6.1. Your website mentions donations, which I wouldn’t be opposed to if it will help support your work on this plugin.
