  2. // It should typically be random data, or bytes that resemble random data such // as the hash of a password. // The number of bytes in the secret key defines the bit-strength of an encryption // algorithm. For example, AES with a 32-byte key is 256-bit AES. Most algorithms // define restrictions on key sizes.
  3. I'm looking to create a reusable function that will generate a random key with printable ACSII characters of chosen length (anywhere from 2 to 1000+).
  4. The rand function generates a random integer. Tip: If you want a random integer between 10 and 100 (inclusive), use rand (10,100). Tip: The mtrand function produces a better random value, and is 4 times faster than rand.
  5. Ways to generate symmetric and asymmetric keys. Ask Question. Cat /dev/random head -n 128 symkeyfile.key Doubt 2: Which method is more random, Method 1 or Method 2? An AES-128 expects a key of 128 bit, 16 byte. To generate such a key, use OpenSSL as: openssl rand 16 myaes.key AES-256 expects a key of 256 bit, 32 byte.

You have to generate 4 32-bit random numbers and then merge them together. Adding will definitely a bad idea, you won't get a uniform distribution but merging in sense of '1th. 32th bit - 1st generated number, 33th. 64th bit - 2nd generated number and so on' will give you uniformly distributed binary number of length 128, as probability of event that any bit equals zero $=$.

About the WLAN Key Generator
The SG WLAN Key Generator is a tool that allows for quick, valid, and strong WEP/WPA key generation. It uses the 94 standard ASCII characters (with codes 32 to 126) for maximum compatability.
To generate a random WEP or WPA key, simply choose the desired key length and one will be generated for you. To generate a key based on a custom passphrase, enter your phrase into either the Custom Key text fields, and its HEX or ASCII equivalent will be generated for you automatically in the other custom text field.
To use any of the generated WEP keys, simply right-click on the appropriate text field (highlight the text if necessary), then choose copy from the pull-down menu, and paste the text whesre applicable.

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'
?>
