How encrypt email title ? ( GnuPG )

Hi,

I'm following my previous post
\ How encrypt email with a GnuPG public key ? [ solved ]

So I managed to encrypt the email body with GnuPG public key.. But I don't figure how I can do the same for the title ?!
\ ThunderBird manage it.. any idea how ?
\ asked on Official Thunderbird forum

Thanks.

@RickC137 They probably use "Memory Hole" (https://github.com/autocrypt/memoryhole/blob/master/specs/draft-memoryhole.md), that's what Enigmail did before.

I'm not entirely sure what you hope to achieve: have a GPG encrypted subject, and have ThunderBird automatically understand that it's encrypted, so it can be automatically decrypted?
Since you're saying you're building software to support this, what are you building? A ThunderBird plugin that can do this? Or just standalone software that you want to make compatible with ThunderBird default way of handling encryption?
