base64-ng 1.2.2

base64-ng 1.2.2

Small ergonomics and hardening patch for the 1.2 encode-acceleration line.

Added

• Added explicit infallible encode convenience helpers for ordinary byte-to-Base64 paths:
  • encode_infallible
  • Engine::encode_vec_infallible
  • Engine::encode_string_infallible
  • matching Profile helpers

Hardened

• Hardened base64-ng-sanitization fixed-size locked secret decode staging.
• Ensures staged decoded plaintext is wiped even if locked allocation fails before the fill closure runs.

Documentation

• Documented infallible encode overflow panic boundaries, including the practical 32-bit large-input case.
• Updated README, SIMD admission notes, release plan, and crate version matrix for the 1.2.2 release scope.

Verification

• Pentest clean.
• GitHub CI green.
• Local release checks passed.
