Computes the hash value of binary data.

Overloads

HashData(Stream, HashAlgorithmName)

When overridden in a derived class, computes the hash value of a specified binary stream by using a specified hashing algorithm.
HashData(Byte[], Int32, Int32, HashAlgorithmName)

When overridden in a derived class, computes the hash value of a specified portion of a byte array by using a specified hashing algorithm.
