sha3sum is a collection of utilities for calculating the Keccak-family of hashes, which includes the SHA-3-family of hashes, for files. sha3sum has one utility per hash function, and for compatibility with busybox a common sha3sum for all SHA-3 hash functions, which distributions should package as a separate package. sha3sum can optionally be compiled into a multi-call binary.
