Requirements
------------

[](#requirements)

PHP7+

Installation
------------

[](#installation)

Include the library in your project using composer:

```
{
    "require-dev": {
        "codecollab/encryption": "^2"
    }
}

```

Usage
-----

[](#usage)

This library provides common interfaces and exceptions for handling crypto in your applications.

### Generating key

[](#generating-key)

Before being able to encrypt/decrypt data a key needs to be generated / added. To generate a new key use:

```
$key = (new \CodeCollab\Encryption\Defusev2\Key())->generate();

```

*Note: keys should always be stored in a secure location and should never be made public.*

*Note: all key share the common `CodeCollab\Encryption\Key` interface.*

### Encrypting

[](#encrypting)

```
$encryptedData = (new \CodeCollab\Encryption\Defusev2\Encryptor($key))->encrypt('the data to encrypt');

```

*Note: all encryptors share the common `CodeCollab\Encryption\Encryptor` interface.*

### Decrypting

[](#decrypting)

```
$decryptedData = (new \CodeCollab\Encryption\Defusev2\Decryptor($key))->decrypt($encryptedData);

```

*Note: all decryptors share the common `CodeCollab\Encryption\Decryptor` interface.*

To decrypt old data encrypted with v1\* of this library use the deprecated:

```
$decryptedData = (new \CodeCollab\Encryption\Defuse\Decryptor($key))->decrypt($encryptedData);

```

Using your current key. For newly encrypted data create a new and separate key.

### Exceptions

[](#exceptions)

This library may emit two different exceptions:

- `\CodeCollab\Encryption\CryptoException`
- `\CodeCollab\Encryption\FraudException`

It is important to properly handle these exceptions in your applications.

#### `CryptoException`

[](#cryptoexception)

This exception gets thrown when a key could not be generated or when a message could not be en- / decrypted because of system errors.

#### `FraudException`

[](#fraudexception)

This exception gets thrown when there has been suspected tampering with messages. This exception should be handled like the message has been tampered with and precautions should be taken.

Upgrading
---------

[](#upgrading)

When upgrading from from v1\* to v2\* of this library there are breaking changes.

It's not possible anymore to generate a new key or encrypt data using the obsolete `CodeCollab\Encryption\Defuse\Key` and `CodeCollab\Encryption\Defuse\Encrypt` classes.

The `CodeCollab\Encryption\Defuse` package has been superseded by the ``CodeCollab\\Encryption\\Defusev2` package.

Decrypting of data is still possible using the deprecated `CodeCollab\Encryption\Defuse\Decrypt::decrypt()` method and will be for the foreseeable future.

It is however *strongly* advised to re-encrypt old data using the new `CodeCollab\Encryption\Defusev2` package.

The workflow for this will be:

- Generate a new key using the new `CodeCollab\Encryption\Defusev2\Key::generate()` method (**But don't overwrite the current key yet!**)
- Decrypt the data using the current key and the `CodeCollab\Encryption\Defuse\Decrypt::decrypt()` method
- Encrypt the data using the new `CodeCollab\Encryption\Defusev2\Encrypt::encrypt()` method with the newly generate key
- Newly encrypted data can now be decrypted using the new `CodeCollab\Encryption\Defusev2\Decrypt::decrypt()` method
