#sha256sum

Support note (2026-09-05): this README is supplementary. The support record is the only capability authority; it separates native compatibility evidence from Wasm policy and smoke evidence. Options mentioned here but not promoted in that record are not compatibility guarantees.

Compute SHA-256 digests for binary input and verify standard checksum files with -c. Supports stdin, multiple files, binary/text compatibility flags, and NUL-delimited output with -z. Verification supports quiet/status-only output, malformed-record warnings, strict parsing, and ignored missing files. -b emits the binary * marker and -t the text-space marker; the last one wins. With --ignore-missing, at least one listed file must still be verified.

With no file operand, the command silently reads stdin until EOF, matching the upstream terminal, pipe, redirection, and explicit - behavior.
