UnverifiedSHA-256 hash verification only validates byte integrity, not the semantic safety of those bytes — a matching diff can still contain logic vulnerabilities or incorrect database migration directions.68% similarUnverified数字签名工程实现中通常先计算消息的密码学哈希（如 SHA-256）再对哈希值签名，因为非对称加密运算开销远大于哈希运算65% similarUnverifiedHash sealing refers to the server computing a cryptographic hash (such as SHA-256) over the byte content of a CSV after building it and persisting the hash together with the export task, so that any change to the batch content produces a different hash value and is thereby detected.63% similarUnverifiedA file fingerprint usually refers to a cryptographic hash computed over the file contents (such as SHA-256), and any byte-level change produces a completely different digest.60% similar
