Veil-10 Stream Cipher

A 10-seed XOR+offset stream cipher, matching JS and PHP implementations. Runs entirely client-side — nothing here is sent to a server.

Not audited crypto. This is a self-rolled demo cipher for learning the technique (see the Secure Vanilla Comms guide) — an obfuscation layer for same-origin apps you fully control, not a substitute for TLS or a vetted cipher in anything that actually needs to resist a serious attacker.
