Great for sending and receiving secure emails! Its not only important for it to be simple for the sender but this makes it super easy on the recipient too. Not clunky, just simply easy and reliable. USA review. Big 'Thank you' to the developers and their support.
в чем логика PGP если вы изначально заставляете логиниться через Google Account??? wtf
FlowCrypt Browser Extension is not approved by Advanced Protection! So Google users with Advanced Protection can't use it.
Hello! when will you guys be set up with outlook? I've used flowcrypt before and it's VERY useful
When will this app be Reverified by Google ?
Trying to import my PGP keys, i got the error "This key is not supported by FlowCrypt yet. Please write us at [email protected] to add support soon. (decrypt error: Error: Encrypted private key is authenticated using an insecure two-byte hash)"". What now? Can I update this authentication hash somehow?
works well - when it works. first test email went through right away. 2nd never arrived. 3rd was received ok, 4th and 5th havent arrived after 3 minutes. so... if you use this you will have to check using another method to make sure the encrypted email arrived at your destinstion -which makes it not very much use. sorry, I would have liked to use it but its not reliable enough.
Honestly, I normally do not write review but WOW, I've tested many options (free) and all worked VERY WELL! Not sure why yours isn't working but to me... it was smooth and easy to test it out! And, yes... I've tested other 2 (no names here) and it was CUMBERSOME, geez! Great Job!
I sent a test email 50 minutes ago and it has not yet been received. Tried again and it has been 15 minutes and not received also. This is disapointing
Does not work at all, gets stuck in a Google sign in page loop, wasted of time installing and trying to fix.
