Random Name Picker
About Random Name Picker
This free & easy-to-use tool allows you to pick a random name (winner) from a list of names (it supports up to 200k names). You will get the winner instantly after the wheel spinning.
Our unique 3-step client & server side Randomness Process Certification improve your credibility for raffles, contests, drawings, giveaways, and promotions, etc.
Our team ever tested 200k names, which cost the server 10-15 seconds to generate the winner. 100k names will cost 5 seconds. If your list is less than 50k names, it should get the winner instantly.
When you click Pick a Random Name button, the tool will submit all names line by line to our server. Then our server will use Python random module to generate one pseudo-random number between 1 to total names. Then it will choose the name with this random number as a winner.
However, it is a different story on actual real-world operations:
We don't want that somebody use our tool to raffle off a prize, but bypass the random process, and record a video to say, "Hey, we picked a random winner by a tool from miniwebtool.com." So we choose a server-side solution.
By using server-side random function, the only thing that the malicious code or a person can change is the data source. For this situation, you can use our 3-step Randomness Process Certification to prove that the whole process is clean and "random."
If you use Random Name Picker for raffles, contests, drawings, giveaways, and promotions, etc., you are encouraged to enable 3-step Randomness Process Certification function to improve your credibility.
For example, you use the name picker to raffle off a prize to 99 people from John Doe No. 001 to 099:
The winner is John Doe No. 090, here is Demo of The Server-side Certification Link.
Our server will store a part of the information, including the winner's name (asterisked), total names, timestamp, and a SHA512 hash code.
This is step 1. When you give this link and the full winner name to your attendees, most people will trust that your raffle is random.
However, what if somebody doesn't like the winner, and want to check whether there are many duplicate John Doe No. 090 in your original name list?
In this case, you can go to step 2 to download your client-side certification file to prove that your data source has no error. Here is Demo of The Client-side Certification File link.
Finally, what if another John Doe doubt you have modified the file?
You can let him go to step 3, use our SHA512 Hash Generator to check the downloaded file. The SHA512 hash code should be the same if the file did not be changed.
A person can use a fake screenshot or video to change the winner name from local computers, but can not change the information stored on our server. With the firmly secure SHA512 Hash, It is almost inconceivable that any modified file can pass step 3 verification.
It is the reason that you can gain more credibility using our 3-step randomness process certification.
Some users want to use the picker many times with the same name list; for example, teachers pick up a name from students. So we use the HTML5 Web Storage technique to make their life easier. With web storage, web applications can store data locally within the user's browser. If you use a public computer and do not want your names stored, you can use private or incognito window from your browser or submit another some Meaningless text. (We only use web storage to store the last submitted information.)
