A pure-Julia implementation of the KangarooTwelve hashing scheme, so named because it consists of 12 rounds of Keccak (TurboSHAKE128) with kangaroo hopping, allowing for parallel tree-ish hashing termed “leaves stapled to a pole”.

This scheme presents a particularly good balance of:

• Simplicity (Keccak + sponge + hopping)
• Security (128-bit)
• Speed (up to ~2bytes/cycle)

It is currently an IETF draft.
