Why
--------------------
The most difference between "public key cryptography" and normal "password protected cryptography" is that the first approach don't ask you to distribute any password to anyone or any unsafe place, e.g. email, chat app, or internet. And, you need an encryption tool that has industrial strength to protect your confidential information.


Additional Features
--------------------
Organise contacts in groups, then fast and efficiently organise dozens of recipients to send and receive email without setup recipients one by one and answer a bunch of boring questions and input repeat info again and again. Encrypt or decrypt a file just requires several taps, it's very efficient, convenient and simple.


Common Tasks
--------------------
a. list all contact groups, list all member of a group.
b. encrypt and decrypt a file.
c. set up recipients and encrypt an email, decrypt an encrypted email.
d. sign and verify file.
