About b2sum
B2sum creates BLAKE2 hashes for files or data streams. A hash is a fixed-length value computed from input data and can be used to check whether two copies match or whether a file has changed. BLAKE2 is the hashing algorithm named in the tool’s description. The supplied evidence does not specify supported BLAKE2 variants, output formatting, verification commands, or handling of multiple files. It also does not describe cryptographic use cases beyond hash generation. B2sum’s documented role is to compute BLAKE2 hashes from file or stream input. The record lists Windows support. Exact options and compatibility details are not included in the available product information.
