paths…
- •
- --algo
hash-algo

hash-format
- Hash format (base16,
nix32, base64,
sri). Default: sri.
- •
- --mode
file-ingestion-method
- How to compute the hash of the input. One of:
- nar (the default): Serialises the input as a
Nix
Archive and passes that to the hash function.
- flat: Assumes that the input is a single file and
directly
passes it to the hash function.

- Show usage information.
- •
- --offline
- Disable substituters and consider all previously downloaded files
