## Description

pbkdf2 through 3.1.6 re-hashes passwords longer than the digest's block
size on every iteration in its JavaScript fallback (lib/sync.js). A
password longer than the block size (64 bytes, or 128 bytes for sha384 and
sha512) is passed to HMAC as the key on every iteration, and HMAC hashes
such keys in full each time. Cost is therefore O(iterations × password
length), and a long password can block the event loop. The fallback is used
by pbkdf2Sync and pbkdf2 on Node.js before 0.12, on Bun (1.0.0 through
1.1.34, and 1.2.6 and later), and on Deno 2.9.0 and later, because their
native pbkdf2Sync fails the library's feature check. It is also used when
lib/sync.js is imported directly. Node.js 0.12 and later, and browser
builds (which use lib/sync-browser.js), are not affected. Applications that
enforce a reasonable maximum password length are not meaningfully affected.
