Looked like a good solution but noticed that its located in Hong Kong.. So Hopefully The Chinese try to help people to protect their info from US/Sionist terror org..
It is just incredible.
Fantastic tool that helped me decrypt an email sent to me and send my first encrypted email myself. I didn't expect that such a seamless integration into the Gmail interface was even possible... all thumbs up!
Incredibly easy to use and set up, and on top of that- any time I have an issue the developer will contact me directly to help me resolve it! I use FlowCrypt for Android as well, can't wait to see how it progresses.
A great idea executed fairly well. Works as it should. Would be good to get a security audit on it from someone, as GPG tends to only be used by people who really need it and as such the application layer is often targeted. The application has a hard time correctly deciphering signatures from a lot of other typical GPG client configurations; not sure what the issue is but the developer is working on it. The application also seems to want to do everything the old ASCII armor way, which no other clients default to any more. There isn't even an option to use GPG/MIME. The net effect of this is that signing messages results in an unsightly mess when sent to people with typical email clients. PGP / GPG is mostly a dead concept these days, which is a shame. Hopefully plugins like this will make it more readily available to typical users.
Perfectly integrated and "just works", enabling privacy (PGP) without the need for technical knowledge.
Super easy to use and works as seamlessly as you would expect. As a long time PGP user mail encryption add-ons have been notoriously hit or miss and still require large user interaction. Flowcrypt just works.
cool
Makes it simple to use PGP encryption in your emails.
Works well and is easy to use! I highly recommend for those who want to make sure only certain people obtain access to their emails. Plus... they may or may not have robots that where blue sandals working for them... Amazing!
