SHA-256 is a member of the SHA-2 cryptographic hash functions designed by the NSA.

SHA stands for Secure Hash Algorithm. Cryptographic hash functions are fine operations run on digital data; by comparing the reckoned" hash"( the affair from prosecution of the algorithm) to a known and anticipated hash value, a person can determine the data's integrity. A one- way hash can be generated from any piece of data, but the data can not be generated from the hash.

With this tool you can see the SHA-256 versions of string values.
