The missing implicit trust to your own S/MIME encryption certificate seems to be solved. A test with iOS 10.3 was successful. Seems you can import your fresh AYAI keys and certificates, turn on S/MIME encryption (and signatures) for your mail account, and start sending encrypted mails, also to yourself.
Some smaller improvements:
All left swipe menu buttons now show a text label in addition to the icon; certificates large view now show valid from and valid to dates; the first access to contacts comes with a comprehensive explanation why the app wants to read them.
If you like my app, enter some nice comment in the App Store. If not, send me an email and I’ll try to help.
New features only this time:
Touch ID to unlock, SHA256 signatures in new certificates, import profiles for archived decryption keys, and a monospace font for the key password display.
Thanks for your feedback and input for improvements.
A correction for compatibility with Mozilla Thunderbird was made:
Certificate serial numbers should not have the leading bit set to 1, otherwise Mozilla apps crash or refuse to set trust levels.
Thanks for a user for finding and reporting this issue.

Generate strong keys and certificates, and distribute them via mails with your communication partners.

Last week, I met friends from Vietnam who were in Germany for a few days. They surprised me with this gorgeous handmade sand picture. It took a week to do it, they said.
