Very easy to use and straightforward. Creator, Tom, also replies to feedback and concerns immediately.
Great app - it does PGP so easy that initially you think there isn't PGP encoding your eMails - but it is.
A very intuitive, effortless PGP plugin. Look forward to the new features.
Easy and fast to use Extension for PGP encryption. Initially I had some problems, but the Tom the creator was extremely helpful.
Easy to set up for a novice. Integrates well with Chrome and is clear to use. All the complicated things happen under the hood. Also, the creator Tom is responsive and extremely helpful!

E o melhor de tudo: caso você tenha algum problema, você pode contar com um suporte fenomenal dos desenvolvedores! Totalmente recomendada! -------------------------- (English version) This excellent extension allows you to send and receive secure e-mails through GMail effortlessly. The configuration process is quick and easy, allowing you to create the necessary keys or reuse keys from somewhere else (in case you already have them). And the best of all: in case you have any issue, you can count on a phenomenal support provided by the developers! Totally recommended!
Easiest encryption ever. Sent an encrypted message to a non-technical friend and they opened it with no instructions on what to do or expect. That is a win in my thinking.
Fácil de usar y muy práctica.
This is a great extension. The most recent version allows the addition of attachments. This is a paid feature free for now. If you need to send private documents a must have. Nice work Tom and developers at cryptup.
Super easy to integrate with gmail, send out confidential message and file to clients and they all love it!
