Method get_encryption_info

src/chat.rs:1192–1229

Returns multi-line text summary of encryption preferences of all chat contacts. This can be used to find out if encryption is not available because keys for some users are missing or simply because the majority of the users in a group prefer plaintext emails. To get more verbose summary for a contact, including its key fingerprint, use [`Contact::get_encrinfo`].
