How to make the required md5 from a string and a number?

Question

JavaScript

There is a number 0.333 = md5: cf3567ceb9cc35aaa3a550227c77a026
I need to get the same hash with the number 0.25, to get the hash they use some string строка:0.25 > конвертируют в md5
. What is this string? and how to make it so that when adding a string and a number, the desired hash comes out?

Answer 1

It's called collision.
To get the same hash, you need to find a collision.
Only for this you need to brute force, all in a row.
Go through millions or billions of options.
Or use smart algorithms to generate collisions.

Answer 2

Brute force. You generate different strings and count the hash. If you matched the given - you're in luck. EMNIP, there are no algorithms for accelerated prefix selection for MD5.
