You can use the above constants to define an alphabet (a set of all characters) for password generation. ('00000'+(Math.random()*(1<<24)|0).toString(16)).slice(-6) will always return a length of 6. though this method will still (rarely) return small numbers that give results like 000cf4 or 0000a7 which is a bit hacky i think. Custom patterns are also supported (like strftime) As of 2015, Append the randomly generated 0 or 1 to the string, key Repeat step 2 and 3 for the desired length of the string A list were you can weigh the possibility for each value. The seed function is used to save the state of a random function so that it can generate some random numbers on multiple executions of the code on the same machine or on different machines (for a specific seed value). For example, lets check if the generated password string of length 12 satisfies the following constraints: In the code snippet below, you may modify the condition that the if statement checks for according to the constraints you define. From the random initialization of weights in an artificial neural network, to the splitting of data into random train and test sets, to the random shuffling of a training dataset in stochastic gradient descent, generating random numbers and harnessing In the code cell above, we use an infinite while loop that runs so long as the password string pwd does not meet the constraints.
