Computes the hash value of binary data.
| 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. |
