b3sum - compute and check BLAKE3 hash
b3sum [FLAGS] [OPTIONS] [FILE]...
Print or check BLAKE3 checksums. With no FILE, or when FILE is -, read standard input. FLAGS: -c, --check Reads BLAKE3 sums from the [file]s and checks them -h, --help Prints help information --keyed Uses the keyed mode. The secret key is read from standard input, and it must be exactly 32 raw bytes. --no-mmap Disables memory mapping. Currently this also disables multithreading. --no-names Omits filenames in the output --quiet Skips printing OK for each successfully verified file. Must be used with --check. --raw Writes raw output bytes to stdout, rather than hex. --no-names is implied. In this case, only a single input is allowed. -V, --version Prints version information OPTIONS: --derive-key <CONTEXT> Uses the key derivation mode, with the given context string. Cannot be used with --keyed. -l, --length <LEN> The number of output bytes, prior to hex encoding (default 32) --num-threads <NUM> The maximum number of threads to use. By default, this is the number of logical cores. If this flag is omitted, or if its value is 0, RAYON_NUM_THREADS is also respected. ARGS: <FILE>... Files to hash, or checkfiles to check. When no file is given, or when - is given, read standard input.
