lib-crypt
=========

[](#lib-crypt)

Shorthand library for using AES encryption provided by PHP-Mcrypt

Usage
-----

[](#usage)

```
use \LSS\Crypt;

//create keys
$iv_key = Crypt::IVCreate();
$crypt_key = Crypt::keyCreate();

$crypt = Crypt::_get($crypt_key,$iv_key);
$crypted_str = $crypt->encrypt('my string'); //returns base64 encoded crypted string
$var = $crypt->decrypt($crypted_str); //returns 'my string'
```

Padding
-------

[](#padding)

By default MCrypt will NULL-PAD strings to get the proper encryption. However this creates problems when expecting exact payload encryption (such as binary)

Crypt deals with this by storing the size of the payload as the first 4 bytes in the returned string Crypt then extracts this size and trims the payload to the original size upon decrypt

The downside to this is that it cant be decrypted by the regular MCrypt functions without first stripping the initial 4 bytes. It would be recommended to trim the payload if possible

Reference
---------

[](#reference)

### (string) Crypt::IVCreate()

[](#string-cryptivcreate)

Returns a proper initialization vector for the encryption type

### (string) Crypt::keyCreate()

[](#string-cryptkeycreate)

Returns a proper secret key for the encryption type

### (object) Crypt::\_get($key,$iv)

[](#object-crypt_getkeyiv)

Shorthand for the construct that returns the new object

### (object) Crypt::setKey($key)

[](#object-cryptsetkeykey)

Change the key at runtime Returns $this so its chainable

### (object) Crypt::setIV($iv)

[](#object-cryptsetiviv)

Change the IV at runtime Returns $this so its chainable

### (object) Crypt::verify()

[](#object-cryptverify)

Verifies the key and IV Will throw exceptions on errors Returns $this so its chainable

### (string) Crypt::encrypt($plain\_string,$base64\_encode=true)

[](#string-cryptencryptplain_stringbase64_encodetrue)

- $plain\_string String to be encrypted
- $base64\_encode TRUE to base64\_encode the encrypted string Returns the encrypted and optionally base64\_encoded string

### (string) Crypt::decrypt($enc\_string,$base64\_decode=true)

[](#string-cryptdecryptenc_stringbase64_decodetrue)

- $enc\_string The encrypted string to be decrypted
- $base64\_decode If the $enc\_string is base64\_encoded set to TRUE Returns the EXACT original string
