since digested information or the hash cannot be reverted back to the raw data, the 256 bit security ,makes it essentially impossible to guess the initial input.

- Secure Hashing Algorithm (SHA) - 256
- It takes any amount of data and turns it into a 32 byte string that will be different if even one character is off, but will always be the same output if the characters are matching. This makes it nearly impossible to reverse-engineer. Imagine taking a 500 page book and inputting it into a SHA-256 algorithm. You could run the book through a thousand times and get he exact same 32 byte string as output a thousand times. But as soon as you misspell one word, or change one character, the output will be different.

- Picking a random number input and then hash it and comparing output with the target until you find a match for it and it takes really long to do!

- SHA-256
- The possibilities of solving the algorithm are very low in most cases would take a lifetime. The process is basically a guessing game until one of the computers in the “network” gets the right answer. By the time the algorithm is solved a new one is created.

What is the hashing algorithm called used in Bitcoin?
SHA256 stands for (Secure Hash Algorithm 256-bit) It’s used for cryptographic security.
Why is this hashing algorithm really hard (almost impossible) to brute-force
SHA256 (Secure Hash Algorithm 256-bit) Can’t be reversed simply because it’s a one way function. Due to its design goal it’s going to take too long time to brute-force.
it’s not worth the time and energy that it will take, it’s in-theory possible but a time estimation is:
“A whole lifetime of a human being”

Unlike SHA-1, SHA-256 does not show any patterns in the hash where a brute force attack has been successful. A SHA-256 hash is almost impossible to crack at present. Even if we were to use all the energy currently available on Earth to try to crack SHA-256, it would not be successful at this time. It seems that until quantum computers are introduced, we are safe with this current hash algorithm.

It’s called “Secure Hash Algorithm” or SHA-256.
- Why is this hashing algorithm really hard (almost impossible) to brute-force?
In cryptography, “to brute-force” means that a hacker is trying to calculate and guess every combination that could result in the correct password. However, SHA-256 operates as a one-way function and that it is also designed to have up to 256 characters; by virtue of this fact, as the password length increases, the amount of time it takes to find the correct password increases EXPONENTIALLY. This makes it practically impossible for the hacker/attacker to guess the password correctly.

- Why is the Hashing Algorithm really hard (Almost Impossible) to brute force?
The Bitcoin Hash Algorithm is only solved in a linear unidirectional manner with no allowance for reversals. There is no way to get to the original raw data (inputs) so there is no digital finger print to go by.

1.- SHA-256
2.- The hashing algorithm is really hard to brute-force by design. Basically, they have been increasing arbitrarily the length of the hash to reach a point that is almost impossible to brute-force with the current technology. If the current technology could brute-force it more easily, they would increase the difficulty even more. In fact, the complexity of the problem is adaptive to the rate at which miners can provide a solution to it and it is reviewed every 2016 blocks.

Varying the nonce’s trial and error process and the chances of success are low. With so many possibilities, mining requires high amounts of computational capacity, as well as dedicated hardware equipment.

This hashing algorithm is really hard to brute-force because of the ridiculously huge number of possibilities to just randomly guess correct. It’s highly infeasible.

- Secure Hash Algorithm (SHA) named: SHA-256.
- Sha256 is unilateral so you can’t find the plaintext with only the hash. It would take a really looooooooooong period of time to brute-force it and when you add salt with a special character it’s almost impossible.

It is practically impossible to reverse engineer the process of the algorithm—from informational output, to informational input.

- because it is unidirectional and impossible to revert, so brute forcing it would mean trying an unlimited number of possible inputs before getting the right output which is not possible
