  1. SHA 256
  2. is hard to brute-force because it takes a lot of computational resources and effort. In order to find a collision it takes centuries to compute.

  1. SHA-256
  2. SHA-256 hashing algorithm has been designed to make it nearly impossible by random brute force. There are 2^256 different possibilities, currently impossible to crack.

The bitcoin Algorithm is SHA-256

The odds against Brute forcing a hash are astronomically overwhelming that it would potentially take so long, that it wouldnā€™t be viable.

  1. What is the hashing algorithm called used in Bitcoin? SHA256
    2)Why is this hashing algorithm really hard (almost impossible) to brute-force? Because the chances mathematically of hitting the exact same 256 bits are definitely against you the possible combinations are too numerous

1 - What is the hashing algorithm called used in Bitcoin?
SHA256

2 - Why is this hashing algorithm really hard (almost impossible) to brute-force?
Because the hashing algorithm is assumed to be one-way and collision proof, the ā€˜simplestā€™ way to find the input that generated a hash is to attempt to test all possible inputs. This is very expensive using current computing technologies due to the number of possible permutations.

  2. Why is this hashing algorithm really hard (almost impossible) to brute-force? Infeasibleā€¦ it would take so much time to come up with the same hash that it is not worth trying to brute force, life is too short.

    2.Using brute force in these amounts of options is literally looking for a needle in a mountain of haystacks,. Would be actually one of the inefficient ways to hack the hashing algorithm.

SHA-256
2)
Because the brute-force method basically means that you have to pick up a random input,
hash it and then compare the output with the target hash and repeat until you find a match.

SHA-256 is a cryptographic hash function which is being used in bitcoin. Tha kind of functions have several features that makes them effecient tool for security. It is deterministic, meaning that the input gives the same hash everytime, which is good for tracking in databases. It works fast and returns quickly which is important at large amount of calculations. Infeasible to decrypt, means decryption is not impossible but when you consider that an hash has 64 characters length value, after digestion of several methods and multiple compression, even it can totally change while only one character in the input changes, It becomes out of matter that encounter input value by comparing random hash strings.

  1. Sha 256 is the hashing algorithm used in Bitcoin
    2.The algorithm hashtag is almost impossible to brute force because it is difficult to find 2 inputs to produce the same output in a hash function.

  2. Because of its function, and the possibilities of finding input to get get the same result is almost imnpossible.

  2. It should take every combination possible, hash it and compare it which takes ages for 1 hash to be dehashed.

  • SHA-256
  • SHA-256 is really hard (almost impossible) to brute force because of the amount of time needed to accomplish. It would take life times.

Bitcoin hashing algorithm is the so called sha256 wich is a algorithm base on 256 caracters length.

2 Why is this hashing algorithm really hard (almost impossible) to brute-force?

Because is very long and takes several time, even years, to find the result

#1126

To brute force it, it would require approximately 2^127 tries
