Ihre Konkurrenz liest mit? Nicht mit S/MIME.

Die Ende-zu-Ende-Verschlüsselung mit S/MIME macht E-Mails für ungebetene Mitleser zum unknackbaren Datensalat.

S/MIME-Signaturen schaffen Klarheit über die Authentizität von Absendern. Und machen Phishing-Angreifern so den Alltag schwer.

Gmail business users can now send encrypted emails to anyone Google says that Gmail enterprise users can now send end-to-end encrypted emails to people who use any email service or platform.

Not promoting Google here because they long ago jumped the shark, but E2E encryption is nice.

How to fix email encryption Jan Wildeboer’s thread on setting up a cooperative CA inspired me to finally write down (and then forget about them again for over a week) my thoughts on a related topic: Email encryption. With PGP and S/MIME, we already have two mature solutions for sending encrypted emails that have been around for decades. And while there are a few issues here and there, we can essentially consider the problem resolved. If it wasn’t for the UX…

@jwildeboer's recent thread about his CA co-op idea inspired me to write down some thoughts on email encryption.

If you need #E2EE via #email, the only 2 valid standards are #OpenPGP and #SMIME.

It's not that those are without issues but everything else is mediocre.

Yes, you can switch to non-email-services as well such as #Signal. But that's a different island.

#AskFedi - I need a new #SMIME #cert for my #email. My old cert has been expired for well over a year now it looks like. Oops. ;-)

Is #GlobalSign still the recommended #CA for globally-trusted SMIME certs?

If not, what CA would you recommend?

U.S. officials urge Americans to use encrypted apps amid cyberattack that exposed live phone calls FBI and CISA officials said it was impossible to predict when the telecommunications companies would be fully safe from interlopers.

"..The hacking campaign, nicknamed Salt Typhoon by Microsoft, is one of the largest intelligence compromises in U.S. history, and it has not yet been fully remediated."

Manchmal ist eine Lösung für ein Problem einfach, aber nicht unbedingt naheliegend.
