Gwaidigo 4+

Reliable, strong, safe.

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as the next generation of the daily cryptography tool because the RSA based on cryptography algorithm is almost out of date. The internal details of Gwaidigo was completely hidden and has builtin multiple cryptography layers for inner data protection that makes it very strong. As a public key crypto-system used for secure file and message transmission, it adopted a customised version of the stable and reliable ECC (Elliptic Curve Cryptography) algorithm used by bitcoin to guarantee the reliableness of the software. The format of the Gwaidigo's public key is NOT public that makes the entire system very strong and very difficult for reverse engineering. Gwaidigo is an encryption and decryption system based on industry strength 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.

General Features
------------------
* Group and key pair management.
* Drag operation for group organisation, easily manage contacts by company and department.
* Seamlessly integrated with the macOS' builtin Mail.app, fast organise dozens of recipients without click one by one.
* Encrypt, decrypt email and file requires only several simple clicks.
* Database export and import, fast switch database (keyring).
* Fuzzy query user name or email from the records of the inner database.
* Fast switch multiple primary keys that helps using with different master identities.
* Automation common tasks with scripting languages.
* Without complex installation, configuration or double boring questions.

Basic Usage
------------------
You don't need to know more about public key encryption at all, you can get industry strength information protection with just a few simple steps.
1. Generate a key pair for yourself.
carefully keeping your private key (security key) and never leak to others except yourself.
2. Distribute your public key.
send your public key to others then they can use it to encrypt email or file.
3. Import other people's public key.
encrypt email or file with their public keys.
4. Decrypt message or file with your own private key.

Additional Usage
------------------
a. Directly encrypt plain text block as an email file.
b. Use with instant chat apps, encrypt plain text block and send to other, the receiver directly decrypt the text block.

Scriptable App
------------------
The main functions of the engine is programmable and can be called from scripting languages, the exported automation interfaces makes the common tasks can be accomplished from command line and other places.
a. list all groups, list all member of a group.
b. encrypt and decrypt a file.
c. set up recipients and then encrypt an email, decrypt an encrypted email.
d. sign and verify file.

Why another cryptography tool?
There should have another cryptography utility that does not adopt RSA algorithm and has industrial strength to protect user confidential information.
