Tool detail

hash

Computes cryptographic hash digests — sha256, sha512, sha1 or md5 — of UTF-8 text or base64-encoded bytes.

Categories: Utilities

Use when

compute a sha256 checksum of a text string
hash raw bytes given as base64 for verification
compute several digest algorithms for the same input in one call

Not for

not a password/hash cracker — verification and checksums only
md5/sha1 are legacy interop only, not for security use

Inputs

POST JSON body: text (string) or bytes (base64 string) — exactly one required; algorithms (array enum sha256/sha512/sha1/md5, optional, default [sha256])
