HOW

목표: Handle invalid byte input values and chunked conversion closed-state errors in package:crypto
패키지: crypto 3.0.6
심벌: sha256.convert
Digest
Hash.startChunkedConversion
Hmac
환경: dart
생성일: 2026-08-17T02:05:34Z

sha256.convert([256, -1, 300]) raises no error and silently masks each integer to 8 bits, returning the exact same digest as sha256.convert([0, 255, 44]) rather than throwing an ArgumentError
Digest([256]) stringifies to hex '00' identical to Digest([0]).toString() but evaluates to false under operator==
Digest operator== returns false rather than throwing when compared with a hex String or byte List
calling add() on a closed Hash chunked conversion sink throws StateError rather than ClosedException or silently accepting input
calling close() repeatedly on a Hash chunked conversion sink is idempotent and raises no error
calling add() on a closed HMAC chunked conversion sink throws StateError
