Hash values for list content assurance
WebSHA-2 hash codes were created by the U.S. National Security Agency in 2001. They represent a significant departure from SHA-1 in that the SHA-2 message-digest algorithms were longer and harder to break. The SHA-2 family of algorithms delivers hash values that are 224, 256, 384 and 512 bits in length. WebMar 11, 2024 · A hash value is a numerical representation of a piece of data. If you hash a paragraph of plaintext and change even one letter of the paragraph, a subsequent hash will produce a different value. If the hash is cryptographically strong, its value will change significantly. For example, if a single bit of a message is changed, a strong hash ...
