Erstklassige Erweiterung, einfach zu handeln und leicht zu integrieren.
Excellent! Finally encryption for dummies! Easy and well thought out. Thank you very much!
Easy to use. Nice work.
Beyond simple to use. You can send encrypted messages even to people who do not have an encryption already set up. Easy to set up. I can't believe this is out there! Thank you so much!!!
very easy to use - really well thought out.
Only been using this for few minutes but I'm extremely impressed, to a point where I already subscribed to their advanced version. Also love how helpful and responsive they are to emails.
Does what it says on the tin with no fuss and trivial setup. As an added bonus, It automatically keeps a backup of my keys that I can transfer to any computer. Highly recommended
would no open on my mac???
This add-on helps you writing encrypted messages using the Pretty Good Privacy (PGP) algorithm. I'm new to this field and I really enjoyed FlowCrypt: It works perfectly and smoothly. And it requires no time to be installed!!!
I have been trying to get a "painless" way to use encryption in my google apps account. After lots of failed attempts, I came across FlowCrypt. The app is amazing and the developers are very helpful and supportive! It worked immediately.
