{"name":"hash-string","description":"Computes cryptographic hash digests of any input string across five algorithms: sha1, sha256 (default), sha384, sha512, and md5. Returns hex, base64, and base64url encodings of each digest. SubtleCrypto powers the SHA family; MD5 is computed by a small in-process implementation (the web crypto spec doesn't expose MD5, but it's still useful for cache keys and content fingerprinting where collision-resistance isn't required). Use it as a string hasher, multi-algorithm digest, cache-key generator, or content fingerprinter for SHA-256 / SHA-1 / SHA-384 / SHA-512 / MD5.","price":"$0.005","method":"POST","input_schema":{"properties":{"text":{"type":"string","description":"Source text to hash.
