//! Twofish single-block encryption with 128-, 192- and 256-bit keys.
//!
//! Variable time: key-dependent S-box and MDS lookups, and key-setup branches,
//! depend on secret data. Use only where timing leakage is outside the threat
//! model; no constant-time alternative is provided. Stored tables and subkeys
//! are wiped on drop, but caller buffers and every register or stack copy
//! are not. No mode, padding or authentication is provided.
