WebJan 3, 2024 · Generating a Hash. The hash classes can hash either an array of bytes or a stream object. The following example uses the SHA-256 hash algorithm to create a hash value for a string. The example uses Encoding.UTF8 to convert the string into an array of bytes that are hashed by using the SHA256 class. The hash value is then displayed to … Web2 Answers Sorted by: 26 Though SHA-256 nominally offers a 256-bit output, no weakness about it is known when the output is truncated to 128 bits, except, of course, weaknesses inherent to the shorter output length; e.g. collision resistance drops from the infeasible 2 128 to the possible (but hard) 2 64.
