SHA-256 - what is it?

SHA-256 is one of the secure hashing algorithms. Today, this technology is considered optimal, taking into account the advantages it provides to users of the cryptocurrency network and the entire system.

SHA-256 is a cryptographic function that can accept and process messages of any length. Calculating a unique hash code brings them to a given length. The name of the function itself implies its performance characteristics. That is, the number 256 indicates that this is the number of bits that any message will be equal to.

Applications and Benefits

The SHA-256 algorithm has proven itself to be excellent in the following applications:

  • checking the integrity of files and messages;
  • generation of digital signatures;
  • maintaining the stable operation of the proof of work mechanism;
  • generation of addresses.

The key advantage of this function is its high resistance to collisions and other attacks based on the principle of data selection. Although newer solutions have been developed and integrated into cryptocurrency networks since the introduction of this encryption algorithm, this function remains viable due to its high efficiency.
