SHA-256 Hash Generator

SHA-256 Hash Generator computes the 256-bit SHA-2 hash of any text input. SHA-256 is the current standard for data integrity verification, digital signatures, certificate fingerprints, and blockchain proof-of-work.

Unlike MD5, SHA-256 is cryptographically strong — no practical collision attacks exist. It is the right choice for checksums on security-sensitive files or for generating fixed-length representations of arbitrary data.

Tip: SHA-256 is deterministic — the same input always produces the same hash. Use it to verify a config file or binary has not changed by storing the hash and recomputing it later.
