The SHA-256 hash generator calculates a hash value for a text entered by using the cryptographic hash function SHA-256 (Secure Hash Algorithm 256). The hash value has a length of 256 bits. A SHA-256 hash is e.g. used to ensure that a text has remained unchanged on the way from its creator to the receiver. Every change of a character leads to an altered SHA-256 checksum. To generate a hash, a text needs to be entered and submitted.
