hash

hash calculates file or text digests, selects algorithms, produces HMAC with a hidden key or key file, verifies an expected digest and supports hexadecimal or Base64 output.

SecurityVersion 1.1.4Stable

Overview

Use a digest to identify or compare data and HMAC when verification must also depend on a secret. The normal output contains only the digest, so it can be copied or redirected without removing labels.

A digest and an HMAC answer different questions

A plain hash detects whether data changed, but anyone who has the data can calculate the same value. HMAC adds a secret key to the check. Neither operation encrypts the input or makes its contents recoverable from the digest.

Syntax

lil-terminal
hash [<file>|-s "<text>"] [-a <algo>] [-h|-K <file>] [-b] · hash -c <digest> <file> [-b]

Reference

hash

list available hashing algorithms

hash <file>

hash <file> -a sha512

select another algorithm

hash <file> -h

calculate HMAC with a hidden key prompt

hash <file> -K <keyfile>

calculate HMAC with a key file

hash -c <digest> <file>

verify a hexadecimal digest

hash -c <digest> <file> -b

verify or print Base64 instead of hexadecimal

Install and manage

Install the current compatible version. Choose Base for the complete feature set or Minimum for the reduced package; use upgrade to update a module that is already installed.

Base and Minimum are two packages of the same current module release, not separate command versions.

Base package

Install the complete package with local command reference and every published mode.

install hash
Minimum package

Install the reduced package. Local reference is omitted; help <cmd> -i opens the current server reference.

install hash -m
Exact public version

Install exactly this published version.

install hash -v 1.1.4
Check or update

Ask upgrade to check compatibility and replace the installed block only when needed.

upgrade hash
Remove module

Remove the extension block while leaving the core and unrelated modules intact.

install hash -u
