The SPPS is a lightweight solution to protect / hide your password or anything else from your code.
## Features
* AES 256 GCM en-/decryption
* Cross programming languages support
* [Java with Bouncy Castle](https://github.com/elomagic/spps-jbc)
* [Java with Apache Shiro](https://github.com/elomagic/spps-jshiro)
* [Python](https://github.com/elomagic/spps-py),
* [Node.js](https://github.com/elomagic/spps-npm)
## Concept
This solution helps one to accidentally publish secrets unintentionally by splitting the secret into an encrypted part
and a private key. The private key is kept separately from the rest, in a secure location for the authorized user only.
The private key is randomized for each user on each system and is therefore unique. This means that if someone has the
encrypted secret, they can only read it if they also have the private key. You can check this by trying to decrypt the
encrypted secret
with another user or another system. You will not succeed.
A symmetrical encryption based on the AES-GCM 256 method is used.

By default, the private key is stored in a file "/.spps/settings" of the user home folder.
Keep in mind that anyone who has access to the user home or relocation folder also has access to the private key !!!!
## Requirements
* Python version 3
* Python module pycryptodome
## Example
```python
import simple_crypt
encryptedSecret = simple_crypt.encrypt_string("My Secret")
print("My encrypted secret is {}".format(encryptedSecret))
secret = simple_crypt.decrypt_string(encryptedSecret)
print("...and my secret is: {}".format(secret))
```
## How to create an encrypted password
Enter following command in your terminal:
```bash
python simple_crypt.py -Secret YourSecret
```
Output should look like:
```
{MLaFzwpNyKJbJSCg4xY5g70WDAKnOhVe3oaaDAGWtH4KXR4=}
```
As a feature, if the private key does not exist, it will be created automatically when you encrypt a new secret!
## How to create a private key
### Create a private key in your home folder:
Important Note: Usually you do not need to execute this command unless you want to create a new private key. Remember, secrets already
encrypted with the old key cannot be decrypted with the new key!
Enter following command in your terminal:
```bash
python simple_crypt.py -CreatePrivateKey
```
The settings file ```'~/.spps/settings'``` in your home folder will look like:
```properties
key=5C/Yi6+hbgRwIBhXT9PQGi83EVw2Oe6uttRSl4/kLzc=
relocation=
```
### Alternative, create a private key on a removable device:
Important Note: Remember, secrets already encrypted with the old key cannot be decrypted with the new key!
Enter following command in your terminal:
```bash
python simple_crypt.py -CreatePrivateKey -Relocation /Volumes/usb-stick
```
The settings file ```'~/.spps/settings'``` in your home folder will look like:
```properties
key=
relocation=/Volumes/usb-stick
```
...and in the relocation folder look like:
```properties
key=5C/Yi6+hbgRwIBhXT9PQGi83EVw2Oe6uttRSl4/kLzc=
relocation=
```
