Отлично работает!
This should include that encrypted emails with attachments cannot be sent without an upgrade, defeating the purpose of it both being free and an encryption program to begin with. Most people who are sending encrypted email are doing so with attachments on there. Program is okay if you're just sending an email by itself, but it should advertise that in order to do more, you have to pay for an upgrade.
This is simply, awesome !!! I send lots of emails with delicate info, and I was looking for something like this...so far I have not seen anything other than very positive. Tom, I appreciate this very much.
CryptUp is the missing link between publicKey/privateKey encryption and web-based e-mail that I've been waiting for for years. Easy to install, easy to use. I'm looking forward to the Android version but that's not going to stop me from using it now on the desktop.
The developer is super responsive and helpful. Sadly, CryptUp didn't quite suit my needs, because I often mix encrypted and unencrypted content in one conversation. When CryptUp is enabled and I'm in a conversation where some (or all) messages are encrypted, the dropdown menu that Gmail usually shows in the top right of each message (reply, forward, print, ...) disappears, and I can only send encrypted mails and attachments. I could not mix encrypted and unencrypted content.
Un plugin indispensable pour les amateurs de GMail nécessiteux de sécu ! J'attends patiemment la sortie de l'appli Android... :) Pour ne rien gâcher, le support est au top, très réactif !
This works great! I've been wanting something like this for years. It's effortless to install and natural to use. Love it!
CryptUp is easy to use, easy to setup and generally rock solid. Thanks
Nice tool, simple, efficient, and very reactive support!
