SHA-256 generator

SHA-256 generator tool generates a SHA-256 hash of 64 characters length for any string input. SHA-256 is a cryptographic hash function designed by the United States National Security Agency and is a U.S. Federal Information Processing Standard. It is a successor to the MD4 and MD5 hash functions. SHA-256 is a one-way hash function, meaning that it is easy to compute the hash value from the message, but it is computationally infeasible to find a message that produces a given hash value. SHA-256 is not collision-resistant, meaning that it is easy to find two different messages that produce the same hash value. SHA-256 is not intended to be used as a cryptographic hash function, but it has been found to suffer from extensive vulnerabilities. It can still be used as a checksum to verify data integrity, but only against unintentional corruption. SHA-256 is fast in software and can be efficiently implemented on a wide variety of hardware. SHA-256 is used in a wide variety of cryptographic applications, and is also commonly used to verify data integrity.
