📛 NAME

Digest::HMAC_SHA1 — Keyed‑Hashing for Message Authentication

🚀 Quick Reference

Use Case	Command	Description
Compute HMAC‑SHA‑1 digest (binary)	hmac_sha1($data, $key)	Functional style — returns raw bytes
Compute HMAC‑SHA‑1 hex digest	hmac_sha1_hex($data, $key)	Functional style — returns hexadecimal string
OO style — create HMAC object	Digest::HMAC_SHA1->new($key)	Returns a new HMAC object with given key
OO style — add data	$hmac->add($data)	Feed data to the HMAC computation
OO style — add file	$hmac->addfile(*FILE)	Feed data from a filehandle
OO style — get binary digest	$hmac->digest	Returns raw binary digest
OO style — get hex digest	$hmac->hexdigest	Returns hexadecimal string
OO style — get base64 digest	$hmac->b64digest	Returns Base64 encoded string

📝 SYNOPSIS

# Functional style
use Digest::HMAC_SHA1 qw(hmac_sha1 hmac_sha1_hex);
$digest = hmac_sha1($data, $key);
print hmac_sha1_hex($data, $key);

# OO style
use Digest::HMAC_SHA1;
$hmac = Digest::HMAC_SHA1->new($key);

$hmac->add($data);
$hmac->addfile(*FILE);

$digest = $hmac->digest;
$digest = $hmac->hexdigest;
$digest = $hmac->b64digest;
