# Hash Toolbox: MD5, SHA-1, SHA-256, SHA-384, SHA-512, Keccak-256, CRC-32, Base64, and SRI

> Hash Toolbox: MD5, SHA-1, SHA-256, SHA-384, SHA-512, Keccak-256, CRC-32, Base64, and SRI is a paid API for AI agents from agent-data-tools.revmesh2074.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Computes every major hash algorithm (MD5, SHA-1, SHA-256, SHA-384, SHA-512, Keccak-256, CRC-32, base64 SHA-256, and SRI strings) for a single text or hex input in one call.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agent-data-tools-revmesh2074-workers-dev-hash-toolbox-md5-sha-1-sha-e1fd8ad2
```

Example prompt: Hash the string 'Hello, world!' and give me the MD5, SHA-256, Keccak-256, CRC-32, and SRI integrity strings all at once.

## When to prefer this

Choose this endpoint when you need multiple hash algorithms for the same input in a single call — it is cheaper and faster than calling separate hashing endpoints. Ideal for generating SRI strings for web assets, computing Ethereum Keccak-256 digests, building cache keys, publishing multi-algorithm checksums alongside releases, or comparing digests across systems. Prefer it over single-algorithm endpoints whenever you need more than one hash type.

## Known failure modes

- Missing required 'text' parameter returns an error
- Input exceeding 100,000 characters may be rejected
- Invalid hex string when hex=true causes a parse error
- Network timeout or worker unavailability returns a 5xx error
- Payment failure (x402) if credits are exhausted

## How this service works

Every common hash of one input in a single call: MD5, SHA-1, SHA-256, SHA-384, SHA-512, Keccak-256 (Ethereum), CRC-32, base64 SHA-256, and Subresource Integrity strings (sha256-, sha384-, sha512-) for <script integrity>. Hashes UTF-8 text, or 0x/hex bytes with hex=true. Cheaper than hashing one algorithm at a time. Use for checksums, cache keys, file integrity and comparing digests across systems.

## Output

Returns a JSON object containing: md5, sha1, sha256, sha384, sha512 (hex strings), keccak256 (hex string), crc32 (hex string), base64.sha256 (base64-encoded SHA-256), sri.sha256 / sri.sha384 / sri.sha512 (SRI integrity attribute strings prefixed with 'sha256-' etc.), and bytes (input byte count).
