A hash chain is a tamper-evident log structure: each record contains the cryptographic hash of the previous record, and any modification to any record causes all subsequent hash verifications to fail, thereby exposing tampering.

VerifiedTamper-proof audit logs can be implemented by borrowing the blockchain hash-chain concept, where each log entry contains the hash of the previous record, and tampering causes the hash chain to break and be detected.76% 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.68% similarUnverifiedAn Integrity Hash is the cryptographic digest of each package recorded in the npm lock file, typically using the SHA-512 algorithm and stored with the sha512- prefix.67% similarUnverifiedThe core technical principle of a cryptographic receipt is to hash the output content, attach a timestamp, then sign it with a private key and encapsulate it as a receipt; anyone can verify the signature with the public key and compare the hash value to determine whether the content has been tampered with.66% similarUnverifiedGit's commit history is an immutable chain linked by cryptographic hash values, where each commit's hash is calculated based on its parent commit's hash.63% similar
