Exceptional product. A must for anyone who loves pgp. This will send everything securely.
Awesome extension. Works perfectly. Had one small issue and Tom fixed it within a few hours. Great support!!
Awesome! Very simple to install and use. I had some folks who had to email me sensitive data (including social security numbers). CryptUp made is really EASY! Thank you!
Efficace et simple, à traduire en français
If you are replying to emails sent to email addresses that are different from the main (i.e. you have other e-mails account forwarded) and you use Send As/From in gmail, this will only use the "primary" key setup in the app, even if you have different keys for different addresses. Though you can Decrypt mail for all keys/accounts loaded. Also when using Secure reply there is no indication of what e-mail address is being used, and as said before if you have different key for different address Dev says this will only use the primary key currently, though this is a planned change. If this improves I'll revisit review.
This is a GREAT app. Thank you, Developers, for making email more secure. Danielle
I use Gmail and was pondering how to send secure email. I was referred to this program and love it! Plus Tom is freaky fast responder as developer, sage and sensei
Simple and easy. In many ways, it is transparent to the end user. Everyone should use this.
Importing existing keys, automated recipient lookup, attachment encryption, sign-only, this extension does it all, with excellent Gmail integration to match. Want to send an encrypted email? Hit the shiny new "Secure Compose" button. Know someone doesn't use PGP? The regular compose button's still there. Not tested, but I don't think CryptUp has smartcard support. Though, I would expect the Chrome extension APIs wouldn't allow for it
I was able to import my existing public key, send and receive encrypted mail without interfering with normal unencrypted mail. There is an option to create and upload key which is nice for new users. I am not aware of other PGP plugins that come even close.
