Thunderbird for Android Community Forum

OpenKeychain is a free and open-source Android app that implements the OpenPGP standard. It lets you manage cryptographic keys and use them to encrypt, decrypt, sign, and verify text, files, and messages so that only the intended recipients can read them and so that authenticity can be checked.

It is no longer actively developed for new features (maintenance mode with security fixes only), though a maintained hard fork called OpenKeyRing exists that continues development and adds features such as S/MIME support.

Hi, I’ve been using Thunderbird Desktop for years with S/MIME encryption. Since S/MIME is not currently supported in Thunderbird Mobile, I can’t use it on my mobile device.

Is S/MIME support planned for a future release?

Thanks.

Hi Folks, I use, as do others I know, Thunderbird for Android. Recently it has decided that the SSL Certificate it accepts for fetching emails is not valid for sending and requires you to accept and make an exception for the certificate. Has anyone else found this? I have tested the certificate, provided by Lets Encrypt, on several servers all claiming SMTP, POP3 an IMAP offer valid certificates. Yet Thunderbird still claims it is a security threat. Can omeone off an answer please? I am currently helping others accept the certificate.

Thunderbird ofr Android is V18.0

Cały czas walczę żeby otworzyć dokument od banku Smime.p7s. Pobrałem ceryifkat .P12 i zainstalowałem na telefonie ale nie wyświetla plików przez wasza pocztę załączników i nie mogę też znaleźć w ustawieniach żeby wgrać ten certyfikat do waszej poczty. Pomocy co zrobić?
