It's an easy tool to use and effective in protecting sent data and attachments.
It really does make using PGP very simple
FlowCrypt is PGP made userfriendly
simple and easy to use
Simple & intuitive
The extension makes rather straightforward the generation of encrypted emails through gmail. Great support too!
No complaints. I've used it for sending sensitive stuff via Gmail and it worked. Works exactly as advertised for me. The key file is exportable to google drive (or wherever you want) and you can import it on any device...as long as you remember your passphrase ;) . Good product.
Makes email encryption much less complicated than the other email encryption tools I have tried. Fantastic product support, too!
Fácil,simples,útil e seguro. Excelente ferramenta.
Funktioniert einwandfrei, ist leicht zu bedienen und übersichtlich. Der Sicherheitslevel ist sehr hoch. Der Support ist gut und schnell. Erlaubt auch die Verwendung eines Ein-Mal-Passwortes, so dass auch an Empfänger ohne ein PGP-PlugIn verschlüsselte Emails versendet werden können. Das macht FlowCrypt für den Einsatz mit Empfängern, die über keine Verschlüsselungstechnik verfügen, zu einer guten und praktikablen Lösung.
