(2) You have a known hash and content and need to verify that the content matches without knowing which algorithm was used — auto-detection from hash length identifies MD5 (32 hex), SHA-256 (64 hex), SHA-512 (128 hex), and BLAKE2b/3 variants. DO NOT USE WHEN: you need a keyed message authentication code — use hmac_gen instead. Do not use for password hashing — use bcrypt, scrypt, or argon2 (this tool produces fast hashes that are unsuitable for password storage). OVER ALTERNATIVES: prefer over crypto.createHash (one algorithm at a time, no verify mode with auto-detection) and online hash tools (no MCP API, no batch algorithm output).","mcpDescription":"Generates and verifies cryptographic hashes. USE WHEN: hashing content for integrity checking, cache keys, or deduplication, or verifying that an input matches a reference hash without knowing which algorithm was used. INPUT: input string, mode, optional algorithms array, optional verify fields. OUTPUT: per-algorithm hashes (generate mode) or match result with detected algorithm (verify mode). COST: 1 unit.","howTo":[{"step":"Choose mode","description":"generate produces hashes for all algorithms. verify confirms a match against a known hash."},{"step":"Enter input","description":"Drop in the text or data to hash (or to verify against the reference hash)."},{"step":"Select encoding","description":"hex (default) for most contexts, base64 for shorter output (URL-safe variant available)."},{"step":"Generate or verify","description":"Generate returns all algorithms simultaneously. Verify returns match status and detected algorithm."}],"faqs":[{"question":"Which algorithm should I use?","answer":"For new applications: SHA-256 or BLAKE3 — both are fast and cryptographically secure. For compatibility with legacy systems: SHA-1 or MD5 (both are broken for security but fine for non-cryptographic purposes like cache keys). For maximum security against future attacks: SHA-512 or SHA-3-512."},{"question":"Is this safe for password hashing?","answer":"No. MD5, SHA, and BLAKE are designed to be fast — exactly the opposite of what password hashing needs. Use bcrypt, scrypt, or argon2 for passwords. This tool is for content integrity, deduplication, and cache keys."},{"question":"How does auto-detection work in verify mode?","answer":"The tool inspects the hash length and character set: 32 hex chars → MD5, 40 hex → SHA-1, 64 hex → SHA-256, 96 hex → SHA-384, 128 hex → SHA-512. Base64-encoded hashes are detected similarly by decoded byte length. If the algorithm is ambiguous (rare), provide verifyAlgorithm explicitly."},{"question":"Can I use this tool via the MCP API?","answer":"Yes. The tool is registered on the obfus.link MCP server at https://obfus.link/mcp. Call it from any MCP-compatible agent with a Shared Payment Token. The MCP tool name matches the snake_case slug shown in the integration snippet."}],"workflowChains":{"live":[],"planned":[]},"tags":["hash","md5","sha256","sha512","blake3","checksum","crypto"],"tddVerified":true,"mcpCostUnits":1}}
