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.71% similarUnverifiedThe 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.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% similarUnverified多行代码块使用三个反引号包裹并触发语法高亮，行内代码块使用单个反引号包裹嵌入正文65% similarUnverified对于代码而言，一个token通常对应3-4个字符63% similar
