Synopsis
========

[](#synopsis)

```
use dbeurive\Cast128\Cast128;

$key = array(0x01, 0x23, 0x45, 0x67, 0x12, 0x34, 0x56, 0x78, 0x23, 0x45);
$data_to_cypher = array(0x01, 0x23, 0x45, 0x67, 0x89, 0xAB, 0xCD, 0xEF); // 32-bit long!
$cypher = new Cast128($key);
$cyphered = $cypher->cypher($data_to_cypher);
$deciphered = $cypher->decipher($cyphered);

```

**The key**: The key is represented by an array of 8-bit integer values (from 0 to 255). The array contains from 5 to 16 values. That is, the length of the key varies from 40 to 128 bits.

**The data to cypher/decipher**: This data is represented by an array of exactly 8 values. That it, the data to cypher is a 32-bit long value.
