Metadata security, monitoring, and display
Encrypt Mail Card encrypts the content of your communications, but will not encrypt the metadata of your email services. In fact, encryption does not hide that you and your friend are communicating, that you are using encryption to communicate and other information such as the subject of your communication, the place, the times.
Reason why, we recommend using encryption even for non-sensitive emails. This is the advantage of this solution compatible with Webmail messaging services. You can use it on an anonymous or ephemeral email address, or use this encryption tool by everyone when possible.
This will make its use normal and not suspicious for those who listen to the networks. Email encryption can be performed offline only on the RAM of the computer and /or phone which will increase the level of security at rest and then in transit.
However, if you send end-to-end encrypted messages by encrypting your data in transit without encrypting your data at rest, this brings another advantage since in principle your messages will be the test of monitoring traffic and listening to the network.
Finally, even if an attacker physically accesses your mobile device or computer, they will not be able to read your encrypted emails.
Encryption keys are only in your Encrypt Mail Cards and in your pocket.
