SpeckHashX

A hash function with any output length, built from the Speck cipher.

• Any length. Ask for 1 byte or 1,000. Each length gives its own unrelated hash.
• Same answer everywhere. One source runs in Rust, Node, Bun and browsers.
• Public domain. CC0, the same terms as Speck itself.

Experimental. This design is new and has not been reviewed by anyone.
