Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.

Example

[Visual Basic, C#, C++] The following example is a method that computes the MD5 hash for data and returns it.

[Visual Basic] 
Function MD5hash(data() As Byte) As Byte()
    ' This is one implementation of the abstract class MD5.
    Dim md5 As New MD5CryptoServiceProvider()
       
    Dim result As Byte() = md5.ComputeHash(data)
       
    Return result
End Function

[C#] 
byte[] MD5hash (byte[] data)
 {
    // This is one implementation of the abstract class MD5.
    MD5 md5 = new MD5CryptoServiceProvider();

    byte[] result = md5.ComputeHash(data);

    return result;
 }

[C++] 
Byte MD5hash (Byte data[]) []
{
    // This is one implementation of the abstract class MD5.
    MD5* md5 = new MD5CryptoServiceProvider();

    Byte result[] = md5->ComputeHash(data);

    return result;
}
