payable
Compute cryptographic hashes / checksums of a string or of raw bytes (base64). Returns lowercase hex for each requested algorithm: sha256 (default), sha512, sha1, md5. SHA via native Web Crypto; md5 and sha1 are offered for legacy interop only and flagged — not for security. POST so the input never lands in a URL/log. Verification/checksums only, not a hash cracker.
