Hashing information security
WebJan 3, 2024 · 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 through insecure channels.
