One of the key features of a cryptographic hash function is that it is one-way, meaning that it is virtually impossible to reverse the process and recover the original input from the hash. This output is known as a 'hash' and is typically represented as a hexadecimal string. It offers a more secure solution and stronger for collusion attacks.ĭecrypting SHA256 can seem like a daunting task, but with the right tools and knowledge, it can actually be quite simple.įirst, it's important to understand that SHA256 is a cryptographic hash function, meaning that it is a mathematical algorithm that takes a string of any length and produces a fixed-length output. SHA256 is one of the most popular hashing/encrypting function, especially after reveal of MD5 vulnerabilities. SHA256 or (SHA-256) stands for 'Secure Hash Algorithm 256-bit' and it is found by National Security Agency (NSA) in the USA. SHA256 is a hashing function that creates a unique 256-bit hash with 64 characters long for every string. In other words, this tool is a combination of SHA256 hash generator and SHA256 decrypter. SHA256 Encrypt/Decrypt is a free online tool for generating SHA256 hashes from strings and decrypting SHA256 hashes to strings.
