Linux/sha3

SHA-3

sudo apt install libdigest-sha3-perl

Default 224 bit algorithm:

sha3sum [file]
sha3sum [file] > [file].sha3-224

sha3-256 bit algorithm:

sha3sum -a 256 [file]
sha3sum -a 256 [file] > [file].sha3-256
sha3sum --algorithm 256 [file]

Default 512 bit algorithm: (default for a lot of other programs, like openhash)

sha3sum -a 512 [file]
sha3sum -a 512 [file] > [file].sha3
sha3sum -a 512 [file] > [file].sha3-512

Check:

sha3sum -c [file].sha3
sha3sum --check [file].sha3
