Tool detail

Agent Payload Tools

Computes a SHA-256, SHA-384, or SHA-512 hash of UTF-8 text for integrity checks, fingerprinting, or cache keys.

Categories: Utilities

Use when

compute a SHA-256 hash of a text string
generate a checksum to verify payload integrity

Not for

not for hashing binary files — text input only
not for HMAC signing — a separate hmac endpoint covers that

Inputs

POST JSON body, both optional: input (UTF-8 text, default empty); algorithm (SHA-256|SHA-384|SHA-512, default SHA-256)
