Generating an AES key. An AES key is a random bitstring of the right length. For a 128-bit AES key you need 16 bytes. For a 256-bit AES key you need 32 bytes. If you need to generate your own AES key for encrypting data, you should use a good random source. The strength of the key depends on the unpredictability of the random.

Notes: WEP encryption uses 24 bit 'Initilization Vector' in addition to the 'secret key'. Therefore, 40 bit WEP can be refered to as 64 bit WEP, and 104 bit can be referedo to as 128 bit, depending on whether the 'initialization vector' is counted or not.

Parameters may seem obvius to some but not for everyone so:
- $data can be as the description says raw or base64. If no $option is set (this is, if value of 0 is passed in this parameter), data will be assumed to be base64 encoded. If parameter OPENSSL_RAW_DATA is set, it will be understood as row data.
- $password (key) is a String of [pseudo] bytes as those generated by the function openssl_random_pseudo_bytes().
- $options as (as for 2016) two possible values OPENSSL_RAW_DATA and OPENSSL_ZERO_PADDING. Setting both can be done by OPENSSL_RAW_DATA OPENSSL_ZERO_PADDING. If no OPENSSL_ZERO_PADDING is specify, default pading of PKCS#7 will be done as it's been observe by [openssl at mailismagic dot com]'s coment in openssl_encrypt()
- $iv is as in the case of $password, a String of bytes. Its length depends on the algorithm used. May be the best way to generate an $iv is by:
<?php
$iv = openssl_random_pseudo_bytes(openssl_cipher_iv_length('your algorithm'));// for example you algorithm = 'AES-256-CTR'
?>
