Worked great. Imported my existing gpg keys. Haven't ran into an issue as of yet. Also auto-lookup is a nice feature.
Great integration. Some nice features: * I had an existing set of GPG keys and CryptUp integrated them smoothly. * Installed on windows box, automatically worked smoothly on macbook. * (disclaimer: the application may have the ability to do this and i didn't see it) The only area for improvement I've seen is that when (PEBKAC) I am composing or forwarding an email in clear text but intended to send it encrypted, AFAIK i must manually copy and paste body/subj/attachmts to the secure compose window. It would be nice for the addin to provide a magic button in the clear text compose that I can click, which transfers the content to a secure compose window and to the extent possible provides an option in the settings to wipe traces of the clear version of the message.
So easy to use and secure! Emailed the developer a question about the security of the extension as soon as I got it, and got multiple responses back very quickly :) Thanks!!
Great Chrome extension! CryptUp makes sending encrypted emails so easy anyone can do it! I highly recommend it!
Super Erweiterung, welche sich sogar optimal in die Gmail webapp integriert. Ist auch für Benutzer ohne tiefes Verständnis einfach zu handhaben und zu verstehen! Ich konnte bisher auch noch keinen Bug feststellen. Kann ich nur absolut weiterempfehlen!
So far so good.
This is a great app that simplifies a very important encryption tool. Give it a try, you won't be disappointed. Also, they are extremely responsive to emails.
Worked great for sending messages between Cryptup users! Setting passwords for non-users was exceptionally easy. Really appreciate that it also encrypts attachments!
Does the crypto in browser! Works for both Gmail and Inbox (in short, I love it).
Useful extension, seamlessly integrated with GMail.
