Represents the abstract class from which all implementations of the MD5 hash algorithm inherit.
For a list of all members of this type, see MD5 Members.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
Hash functions map binary strings of an arbitrary length to small binary strings of a fixed length. A cryptographic hash function has the property that it is computationally infeasible to find two distinct inputs that hash to the same value; that is, 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.
[Visual Basic, C#, C++] The following example computes the MD5 hash for data and stores it in result. This example assumes that there is a predefined constant DATA_SIZE.
[Visual Basic] Dim data(DATA_SIZE) As Byte ' This is one implementation of the abstract class MD5. Dim md5 As New MD5CryptoServiceProvider() Dim result As Byte() = md5.ComputeHash(data) [C#] byte data = new byte[DATA_SIZE]; // This is one implementation of the abstract class MD5. MD5 md5 = new MD5CryptoServiceProvider(); byte result = md5.ComputeHash(data); [C++] Byte data = new Byte[DATA_SIZE]; // This is one implementation of the abstract class MD5. MD5* md5 = new MD5CryptoServiceProvider(); Byte result = md5->ComputeHash(data);
