About SHA-256

SHA-256 is a cryptographic hash function that generates a 256-bit hash value from data of any length. It is part of the SHA-2 family and is used for file tamper detection, data integrity checks, digital signatures, certificates, blockchains, and many other purposes.

In DenCode, the entered text is treated as a byte sequence in the selected character encoding, and the SHA-256 hash value is displayed as 64 hexadecimal digits.

For example, the SHA-256 hash value of "Hello, world!" is as follows.

Hash value characteristics

SHA-256 always generates the same hash value from the same input. If the input changes even slightly, the output hash value changes significantly.

A hash function is a one-way function, so the original input data cannot be restored from the hash value.
