SHA256 is a part of the SHA-2 (Secure Hash Algorithm 2) family of one-way cryptographic functions, developed in 2001 by the United States National Security Agency (NSA). Hashing functions are cryptographic devices that take as input any string of characters or a file of any type, and then output a computed collision-resistant hash.
Aug 28, 2014 Feb 08, 2016 · SHA-256 is not a secure password hashing algorithm. SHA-512 neither, regardless of how good it has been salted. Why not? Because both can be computed in the billions per minute with specialised hardware. If you are surprised to hear that you should continue reading What makes a good password hashing algorithm? Sep 12, 2019 · SHA-256 is a patented cryptographic hash function that outputs a value that is 256 bits long. What is hashing? In encryption, data is transformed into a secure format that is unreadable unless the recipient has a key. In its encrypted form, the data may be of unlimited size, often just as long as when unencrypted. Sha-256 is, to the best of my knowledge, still used and considered secure. However, there was an attack found on sha1 that people believe may hint at a vulnerability in sha2, so researches came up with the new sha3 algorithm. I hope I explained this well. I will reread this once I've gotten some sleep and edit it to make it more logical if needed. SHA-256, which became the successor of SHA-1, bears another name-SHA-2. It's not much harder to encode than SHA-1, and its 256-bit key has never been compromised so far. Secure communications for websites and web services are based on files known as certificates. They are used to establish and authenticate secure connections.

It is moderately secure for authentication and verification. Cryptographic hashes work by using one-way 1:many functions that have the property of there being no trivial relationship between changes in input and changes in output.
