Add option to force E2EE encryption preference

Enabling this option ignores Autocrypt recommendation taking others encryption preferences into account and overrides it with our own encryption preference when possible. This is similar to user always manually enabling/disabling encryption manually in a classic Autocrypt-capable MUA UI whenever the control is not disabled. The goal is to allow encrypting responses to MUAs which can send Autocrypt header but don't support setting encryption preference, such as Thunderbird 91.

+Changes to the UIs
+------------------
+
+- The secondary self addresses (see below) are shown in the UI, but not editable.
+
+- When the user changed the email address in the configure screen, show a dialog to the user, either directly explaining things or with a link to the FAQ (see "Other" below)
+
+Changes in the core
+-------------------
+
+- We have one primary self address and any number of secondary self addresses. `is_self_addr()` checks all of them.
+
+- If the user does a reconfigure and changes the email address, the previous address is added as a secondary self address.
+
+  - don't forget to deduplicate secondary self addresses in case the user switches back and forth between addresses).
+
+  - The key stays the same.
+
+- No changes for 1:1 chats, there simply is a new one
+
+- When we send a message to a group, and the primary address is not a member of a group, but a secondary address is:
+  
+  Add Chat-Group-Member-Removed=<old address> and Chat-Group-Member-Added=<new address> headers to this message
+
+  - On the receiving side, make sure that we accept this (even in verified groups) if the message is signed and the key stayed the same
+
+Other
+-----
+
+- The user is responsible that messages to the old address arrive at the new address, for example by configuring the old provider to forward all emails to the new one.

link2xt	bd81ecdb5d	Add option to force E2EE encryption preference Enabling this option ignores Autocrypt recommendation taking others encryption preferences into account and overrides it with our own encryption preference when possible. This is similar to user always manually enabling/disabling encryption manually in a classic Autocrypt-capable MUA UI whenever the control is not disabled. The goal is to allow encrypting responses to MUAs which can send Autocrypt header but don't support setting encryption preference, such as Thunderbird 91.	2021-11-28 16:32:18 +00:00

Simon Laux	416bf3a829	generate qr code svg (#2815 ) * generate qr code svg prototype * qr code for groups fix formatting * - letter avatar in qrcode - escape xml in userinput (display/groupname) - fix "Me" display name - merge import declarations * remove dot at the end of VerifyContactQRDescription * if addr == displayname, show only one of them Especially useful for yggmail accounts without usernames, because the text would overflow otherwise. * use real clipPath for rounded avatar * - center avatar text better (dominant-baseline) - add "sans-serif" to font fallback for text if arial is missing * make corner always blue * add [logo + "get.delta.chat"] footer to qrcode * Update deltachat-ffi/deltachat.h Co-authored-by: bjoern <r10s@b44t.com> * Apply suggestions from code review Co-authored-by: bjoern <r10s@b44t.com> * new card design - add stockstrings - update changelog * make qrcode pixels also #f2f2f2 instead of full white * rename VERIFY_CONTACT_QR_DESC to SETUP_CONTACT make footer text a tiny bit darker upon r10s's request * avoid using which is a doxygen command * point out that one will join a group (this is still shorted and was also suggested in recent chats) * add option to generate qr-code-svg to repl tool * use same font-family in text and footer * thinner card border * remove superfluous <tspan> from footer to make color tweaking easier * move font-weight to style, ios renderer does not pick it up from attribute; remove default font attributes not used consequently * make get.delta.chat more visible * align properly using dominant-baseline=central and alignment-baseline=middle, this makes things nice on all systems but android (before, ios was wrong and all others not 100% aligned as font metrics are ignored) (android needs a subsequent improvement) Co-authored-by: bjoern <r10s@b44t.com>	2021-11-24 23:23:01 +01:00
