Random Number Generator

The CSRNG Random Number Generator API generates random numbers in JSON format. Calling the 'lite' version without any parameters will return a single random number ranging between 0 and 9,007,199,254,740,991 inside a JSON response. A paid 'Pro' version is also available which returns the random number plus other information regarding the request. The Visa Card Generator generates valid Visa credit card numbers and all the necessary details of an individual account like Name, Country, CVV, and Expiry Date. Apart from a single Visa credit card, you can also generate multiple Visa credit card numbers using our Credit Card Generator. Each card number will hold a unique set of information.

Its the core of all randomness. Pick a number or generate a whole sequence of numbers within a minimum and maximum value (inclusive) while including or suppress duplicates. Your device is used to quickly generate these numbers, completely random and unique to you every time.

Change the quantity to one if you just want it to pick a number.

You can switch the presentation to roll some dice instead. Or change gears completely with the phone number generator or random letter generator.

Random Support Generator

This version of the generator creates a random integer. It can deal with very large integers up to a few thousand digits.

Comprehensive Version

Random Number Generator Verilog

This version of the generator can create one or many random integers or decimals. It can deal with very large numbers with up to 999 digits of precision.

A random number is a number chosen from a pool of limited or unlimited numbers that has no discernible pattern for prediction. The pool of numbers is almost always independent from each other. However, the pool of numbers may follow a specific distribution. For example, the height of the students in a school tends to follow a normal distribution around the median height. If the height of a student is picked at random, the picked number has higher chance to be closer to the median height than being classified as very tall or very short. The random number generators above assume that the numbers generated are independent of each other, and will be evenly spread across the whole range of possible values.

A random number generator, like the ones above, is a device that can generate one or many random numbers within a defined scope. Random number generators can be hardware based or pseudo-random number generators. Hardware based random-number generators can involve the use of a dice, a coin for flipping, or many other devices.

A pseudo-random number generator is an algorithm for generating a sequence of numbers whose properties approximate the properties of sequences of random numbers. Computer based random number generators are almost always pseudo-random number generators. Yet, the numbers generated by pseudo-random number generators are not truly random. Likewise, our generators above are also pseudo-random number generators. The random numbers generated are sufficient for most applications yet they should not be used for cryptographic purposes. True random numbers are based on physical phenomenon such as atmospheric noise, thermal noise, and other quantum phenomena. Methods that generate true random numbers also involve compensating for potential biases caused by the measurement process.
