# Ubiq Security Python Library


The Ubiq Security Python library provides convenient interaction with the
Ubiq Security Platform API from applications written in the Python language.
It includes a pre-defined set of classes that will provide simple interfaces
to encrypt and decrypt data

## Documentation

See the [Python API docs](https://dev.ubiqsecurity.com/docs/api).

## Installation

#### Using the package manager:
You may want to make sure you are running the latest version of pip3 by
first executing
```sh
pip3 install --upgrade pip
```

You don't need this source code unless you want to modify the package. If you just want to use the package, install from PyPi using pip3, a package manager for Python3.

```sh
pip3 install --upgrade ubiq-security
```


#### Installing from source:
From within the cloned git repository directory, Install from source with:


```
cd ubiq-python
python3 setup.py install
```
You may need to run the python3 commands above using sudo.


### Requirements

-   Python 3.5+

## Usage

The library needs to be configured with your account credentials which is
available in your [Ubiq Dashboard][dashboard] [credentials][credentials].   The credentials can be
explicitly set, set using environment variables, loaded from an explicit file
or read from the default location [~/.ubiq/credentials]


```python
import ubiq_security as ubiq
```

### Read credentials from a specific file and use a specific profile 
```python
credentials = ubiq.configCredentials(config_file = "some-credential-file", profile = "some-profile")
```


### Read credentials from ~/.ubiq/credentials and use the default profile
```python
credentials = ubiq.configCredentials()
```


### Use the following environment variables to set the credential values
UBIQ_ACCESS_KEY_ID  
UBIQ_SECRET_SIGNING_KEY  
UBIQ_SECRET_CRYPTO_ACCESS_KEY  
```python
credentials = ubiq.credentials()
```
### Explicitly set the credentials
```python
credentials = ubiq.credentials(access_key_id = "...", secret_signing_key = "...", secret_crypto_access_key = "...")
```



### Handling exceptions

Unsuccessful requests raise exceptions. The class of the exception will reflect
the sort of error that occurred. Please see the [Api Reference](https://dev.ubiqsecurity.com/docs/api#exceptions)
for a description of the error classes you should handle, and for information on 
how to inspect these errors.


### Encrypt a simple block of data

Pass credentials and data into the encryption function.  The encrypted data
will be returned.  The plaintext input needs to be an instance of either bytes, bytearray or memoryview
objects.


```python
import ubiq_security as ubiq

encrypted_data = ubiq.encrypt(credentials, plaintext_data)
```

### Decrypt a simple block of data

Pass credentials and encrypted data into the decryption function.  The plaintext data
will be returned.   The encrypted input needs to be an instance of either bytes, bytearray or memoryview
objects.

```python
import ubiq_security as ubiq

plaintext_data = ubiq.decrypt(credentials, encrypted_data)
```


### Encrypt a large data element where data is loaded in chunks

- Create an encryption object using the credentials.
- Call the encryption instance begin method
- Call the encryption instance update method repeatedly until all the data is processed.
The input data element must be an instance of either bytes, bytearray or memoryview objects.
- Call the encryption instance end method


```python
import ubiq_security as ubiq

# Process 1 MiB of plaintext data at a time
BLOCK_SIZE = 1024 * 1024

# Rest of the program
....

   encryption = ubiq.encryption(credentials, 1)

   # Write out the header information
   encrypted_data = encryption.begin()

   # Loop until the end of the input file is reached
   while True:
       data = infile.read(BLOCK_SIZE)
       encrypted_data += encryption.update(data)
       if (len(data) != BLOCK_SIZE):
          break

   # Make sure any additional encrypted data is retrieved from encryption instance
   # and resources are freed
   encrypted_data += encryption.end()

```


### Decrypt a large data element where data is loaded in chunks

- Create an instance of the decryption object using the credentials.
- Call the decryption instance begin method
- Call the decryption instance update method repeatedly until all the data is processed
The input data element must be an instance of either bytes, bytearray or memoryview objects.
- Call the decryption instance end method


```python
import ubiq_security as ubiq

# Process 1 MiB of encrypted data at a time
BLOCK_SIZE = 1024 * 1024

# Rest of the program
....

    decryption = ubiq.decryption(creds)

    # Start the decryption and get any header information
    plaintext_data = decryption.begin()

    # Loop until the end of the input file is reached
    while True:
    	data = infile.read(BLOCK_SIZE)
        plaintext_data += decryption.update(data)
        if (len(data) != BLOCK_SIZE):
            break

    # Make sure an additional plaintext data is retrieved and
    # release any allocated resources
    plaintext_data += decryption.end()
