Hash file

POST /api/hash-file

Compute SHA-1, SHA-256, SHA-384, or SHA-512 hash of a file. Returns the digest in hex. The standard primitive for content fingerprinting and integrity checks.

Returns the cryptographic hash of arbitrary file bytes in hex. Use this for content fingerprints, dedup keys, integrity checks against a known-good digest, etc. Algorithms: `sha-1`, `sha-256` (default), `sha-384`, `sha-512`. Hashing is one-way: there is no inverse. Two different inputs will (with overwhelming probability) produce different digests.

Inputs

Name	Type	Default	Description
data*	file	—	Bytes to hash.
algorithm	enum (SHA-1 \| SHA-256 \| SHA-384 \| SHA-512)	"SHA-256"	Hash algorithm.

Response

Modes: json. Cache: yes (24h TTL).
