Awesome plugin. Had a few little niggles getting it working properly with an existing keypair, but the human support was fantastic. Highly recommended.
Incredibly easy to use and setup, will recommend to all my privacy minded friends
Wow, finally something that works with Google Inbox. Giving it four stars because it needs to communicate what options do more clearly to users that don't know PGP. Little details, important for adoption. For example: Is the exported key protected with the passphrase I just entered? Intuition says yes, because it's literally the first thing you have to do, and exporting the key is the second thing I did. But prior knowledge says no. The text is not clear. My friends say it's still too vague. I desperately want PGP to become mainstream. Then my bank, municipality, government, health care, tax agency and more can stop sending me emails saying "Please log in to fetch your message" for "safety reasons", and just send me good darn messages to my inbox.
Convenient, fancy and relatively simple. Very responsive team, momentarily helped with a minor issue.
No hassle configuration using existing keys, worked flawlessly in both gmail and 3rd party mail client
Awesome PGP plugin. Works beautifully with GMail.
seems really good so far, it makes pgp encryption really easy davvero bello e semplice, merita di provarlo!
trusted solution
Nice and easy to set up and use. Some features missing but confident the developer will deliver these over time. e.g. easier revocation, sign & encrypt
Amazing extension! Love that I don't have to stop using the GMail web interface and the team was very helpful in responding to any issues I had.
