Php Generate Key From String
Based on your input, get a random alpha numeric string. The random string generator creates a series of numbers and letters that have no pattern. These can be helpful for creating security codes.

(Specifically a Key object, so that I can use it to create a Cipher in turn to create a SealedObject).
Driver tuner 4.5 key generator. With this utility you generate a 16 character output based on your input of numbers and upper and lower case letters. Random strings can be unique. Used in computing, a random string generator can also be called a random character string generator. This is an important tool if you want to generate a unique set of strings. The utility generates a sequence that lacks a pattern and is random.
Definition and Usage. The uniqid function generates a unique ID based on the microtime (the current time in microseconds). Note: The generated ID from this function does not guarantee uniqueness of the return value! To generate an extremely difficult to predict ID, use the md5 function.
Throughout time, randomness was generated through mechanical devices such as dice, coin flips, and playing cards. A mechanical method of achieving randomness can be more time and resource consuming especially when a large number of randomized strings are needed as they could be in statistical applications. Computational random string generators replace the traditional mechanical devices.
Possible applications for a random string generator could be for statistical sampling, simulations, and cryptography. For security reasons, a random string generator can be useful.

A Random Value RAND or RAND( N ) where N is the seed - Generates a random number between 0.0 and 1.0. See this Page on mysql.com A Unique. This is a short guide on how to generate a random token with PHP. These kind of tokens are used for a number of different reasons: To protect against Cross-Site Request Forgery. These are often referred to as CSRF tokens. To help verify a user’s email address. You send the user’s email address a link that contains a “random” token.
In statistical theory, randomization is an important principle with one possible application involving survey sampling.
