`digest::Update`, `FixedOutput`, and `Mac` are infallible; hardware backends are forced to panic when operations fail

#2366

· MarkAtwood opened

on Apr 5, 2026

`RngCore::fill_bytes` is infallible; hardware RNG failure cannot be surfaced — `TryCryptoRng` is the fix and needs to be the primary recommended path

#2364

· MarkAtwood opened

on Apr 5, 2026

The `UnsafeCell` pattern for FFI-backed `Signer`/`Verifier` is correct but undocumented

#2365

· MarkAtwood opened

on Apr 5, 2026

`pbkdf2::pbkdf2` has an unconditional `PRF: Sync` bound; correctly `\!Sync` MAC types cannot use it even single-threaded

#2361

· MarkAtwood opened

on Apr 5, 2026

`pbkdf2_hmac` requires low-level digest internals that opaque FFI backends structurally cannot provide

#2362

· MarkAtwood opened

on Apr 5, 2026

`SignatureEncoding::Repr` cannot represent variable-length or large post-quantum signatures

#2363

· MarkAtwood opened

on Apr 5, 2026

No traits for HKDF or PBKDF2; alternative backends cannot interoperate with generic callers

#2359

· MarkAtwood opened

on Apr 5, 2026

No non-allocating separate-input/output AEAD interface; `AeadInPlace` is the only option for allocation-free code

#2360

· MarkAtwood opened

on Apr 5, 2026

`KeyInit` and related traits impose no `ZeroizeOnDrop` requirement on key-holding types

#2358

· MarkAtwood opened

on Apr 5, 2026

Infallible constructors prevent FFI and hardware backends from reporting initialization failures

#2357

· MarkAtwood opened

on Apr 5, 2026

password-hash 0.6 Argon2 verification fails for PHC hashes with non-default output lengths

Can we have AsyncVerifier please
