Crate tc_threefish 

Threefish tweakable single-block ciphers.

The 256-, 512- and 1024-bit variants require a block-sized key and an optional 16-byte tweak. An absent tweak is equivalent to sixteen zero bytes.

ThreefishEngine and its aliases use ThreefishPortableEngine, a portable engine after Bouncy Castle. The rustcrypto feature adds ThreefishRustCryptoEngine, backed by RustCrypto’s threefish crate, which ThreefishEngine then uses. The alloc feature adds ThreefishParamsOwned, which owns its key and tweak and wipes them on drop.

ThreefishParamsRef

A borrowed key with an optional borrowed tweak.

ThreefishPortableEngine

Portable Threefish after Bouncy Castle, with a compile-time block width.

ThreefishRustCryptoEngine

Threefish backed by RustCrypto’s threefish crate, enabled with rustcrypto.
