public abstract class SHA1 : HashAlgorithm


The hash is used as a unique value of fixed size representing a large amount of data. Hashes of two sets of data should match if the corresponding data also matches. Small changes to the data result in large, unpredictable changes in the hash.

The hash size for the System.Security.Cryptography.SHA1 algorithm is 160 bits.
