Hash Blake2B

BLAKE2b cryptographic hash function generates secure 512-bit digests faster than SHA-3. Access via MCP in Cursor or Windsurf, or REST at GET /v1/hash/blake2b with text parameter. Returns hexadecimal hash like "ba80a53f981c4d0d6a2797b69f12f6e94c212f14685ac4b74b12bb6fdbffa2d17d87c5392aab792dc252d5de4533cc9518d38aa8dbf1925ab92386edd4009923". BLAKE2b offers excellent security with superior performance.

API Endpoint

FAQ

What makes BLAKE2b different from SHA-256 or MD5?

BLAKE2b is faster than SHA-3, more secure than MD5/SHA-1, and produces 512-bit hashes compared to SHA-256's 256-bit output. It's designed for high performance while maintaining cryptographic security.

How do I generate BLAKE2b hashes in my AI agent using MCP?

Connect to TinyFn's MCP server in Cursor or Claude Code, then call the blake2b hash tool with your text input. The agent gets deterministic hash results instead of generating potentially incorrect hashes.

Can I use BLAKE2b for password hashing or sensitive data?

BLAKE2b is cryptographically secure for general hashing, but use specialized password hashing functions like Argon2 or bcrypt for passwords due to their built-in salt and iteration features.

What's the output format and length of BLAKE2b hashes?

Returns 128-character hexadecimal string representing the 512-bit (64-byte) hash. Always deterministic - same input produces identical hash every time.

Is BLAKE2b suitable for file integrity verification?

Yes, BLAKE2b excels at integrity checking due to its speed and collision resistance. It's faster than SHA-2 family while providing equivalent security for detecting file corruption or tampering.
