A rolling hash (also known as recursive hashing or rolling checksum) is a hash function where the input is hashed in a window that moves through the input. A few hash functions allow a rolling hash to be computed very quickly—the new hash value is rapidly calculated given only the old hash value, the old value removed from the ... WebNov 6, 2024 · The MD5 is considered to be cryptographically broken and can be attacked by an average computer. In terms of speed, the MD5 is slightly faster than SHA-2. Therefore, the MD5 is often used as a checksum for verifying files integrity. To sum up, in most cases, SHA-2 will do better than MD5. lannaluo宝箱
