Gwaidigo

Gwaidigo is a general purpose cryptography tool that can be used to encrypt, decrypt email, file, sign and verify files. It was designedly developed as the next generation of the daily cryptography tool on macOS because the RSA based on cryptography alogrithmn is almost out of date. It's internal details was completely hidden and has builtin multiple cryptography layers for inner data protect that makes it very strong. As a public key cryptosystem used for secure file and message transmission, it was completely adopted a customised version of the stable and reliable ECC (Elliptic Curve Cryptography) alogrithmn used by bitcoin to guarantee the reliableness of the software. Gwaidigo is an encryption and decryption system based on industry standard that can ensure the complete security of business negotiations or personal messages. It was developed to make the daily cryptography works on macOS easy and efficient.

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.

Scriptable App
----------------
Automation common tasks with scripting languages.
