MD5 and SHA-1 are insecure because it is possible in practice to find collisions. SHA-512 and the other SHA2 variants (SHA-256, SHA-384, etc.) have collisions. We know this by applying a very simple mathematical theorem, the pigeonhole principle. A SHA-512 hash is a 64-byte string. how to make a big life decision

"WebNov 7, 2015 · Fixed length is no special property from the cryptographically secure part. It comes from the more general specification of hash functions.

WebJan 3, 2024 · A hash value is a numeric value of a fixed length that uniquely identifies data. Hash values represent large amounts of data as much smaller numeric values, so they are used with digital signatures. You can sign a hash value more efficiently than signing the larger value. Hash values are also useful for verifying the integrity of data sent ...

The keys may be fixed length, like an integer, … WebHashing is the transformation of a string of character s into a usually shorter fixed-length value or key that represents the original string. Hashing is used to index and retrieve items in a database because it is faster to find the item using the shorter hashed key than to find it using the original value. It is also used in many encryption ...

WebMar 28, 2024 · I was told that a hash function (mostly looking at the SHA-* family) should have input strings of variant length provided first, and those of fixed length after (ie salt), in order to avoid some kind of collision attacks.
