Unverified50% confidenceSolutionExact time
The self-describing nature of Multihash means that when upgrading the hash algorithm from SHA-256 to SHA-3, identifiers for existing data can still be correctly parsed without ambiguity.

UnverifiedThe Multihash specification prepends algorithm identifier and length information to hash values, giving hash strings self-describing capability so that the parsing party can recover the digest's meaning without prior agreement on the algorithm.77% similarUnverified通过对系统提示内容生成 SHA-256 等哈希值并公开，用户可在不获取明文的前提下验证提示词版本未被篡改70% similarUnverifiedThe Multihash encoding format is typically <varint algorithm code><varint digest length><digest bytes>, with the algorithm code for SHA2-256 being 0x12.70% similarUnverifiedSHA-256 is a one-way hash function that generates a fixed-length 256-bit digest for any input and is computationally irreversible; salting refers to appending a random string to the original content before hashing to prevent rainbow table reverse lookups.67% similarUnverifiedGit采用基于内容的SHA-1哈希值的内容寻址存储模型，每次提交都会生成哈希，任何改动都会产生不同哈希65% similar
