Syntax

public static class HashUtils

Methods

Sha256Hex(byte[], int?)

Hashes bytes with SHA-256 and returns the digest — or a leading slice of it — as lowercase hex.

Declaration

public static string Sha256Hex(byte[] bytes, int? byteCount = null)

Parameters

Type	Name	Description
byte[]	bytes	The bytes to hash.
int?	byteCount	How many leading digest bytes to render as hex, or null for the full 32-byte digest. A caller that only needs a short, collision-tolerant suffix or lock name (never persisted identity spanning a full digest) can ask for fewer; clamped to the digest's own length when larger.

Returns

Type	Description
string	The digest hex — 64 lowercase characters for the default full digest, or byteCount * 2 when given — or empty when bytes is null.
