xxHash API approach

The following snippet demonstrates computing the XXH32 hash value of the input string "test".

byte[] input = Encoding.ASCII.GetBytes("test");     // the data to be hashed
uint result = XXHash.XXH32(input);                  // compute the XXH32 hash value. => '1042293711'
                                                    // NOTE:
                                                    //   you can specified seed as the second parameter.

The following snippet computes the XXH32 hash value of the input file "test.doc".

Stream stream = File.OpenRead(@"C:\test.doc");      // the data to be hashed
XXHash.State32 state = XXHash.CreateState32();      // create and initialize a xxH states instance.
                                                    // NOTE:
                                                    //   xxHash require a xxH state object for keeping
                                                    //   data, seed, and vectors.
                                                    
XXHash.UpdateState32(state, stream);                // puts the file stream into specified xxH state.

uint result = XXHash.DigestState32(state);          // compute the XXH32 hash value.
Supported xxHash APIs:
| original xxHash API name | XXH32                    | XXH64                    |
|--------------------------|--------------------------|--------------------------|
| XXH*nn*()                | XXHash.XXH32()           | XXHash.XXH64()           |
| XXH*nn*_state_t          | XXHash.State32           | XXHash.State64           |
| XXH*nn*_createState()    | XXHash.CreateState32()   | XXHash.CreateState64()   |
| XXH*nn*_freeState()      | *Not implemented*        | *Not implemented*        |
| XXH*nn*_reset()          | XXHash.ResetState32()    | XXHash.ResetState64()    |
| XXH*nn*_update()         | XXHash.UpdateState32()   | XXHash.UpdateState64()   |
| XXH*nn*_digest()         | XXHash.DigestState32()   | XXHash.DigestState64()   |
HashAlgorithm approach

In addition, the assembly also provides XXHash32 and XXHash64 the two implementation classes of System.Security.Cryptography.HashAlgorithm.

The following snippets demonstrate computing the XXH32 hash value with HashAlgorithm approach.

byte[] input = Encoding.ASCII.GetBytes("test");        // the data to be hashed.
using (HashAlgorithm xxhash = XXHash32.Create())
{
  byte[] result = xxhash.ComputeHash(input);           // compute the hash.
}

-- or --

byte[] input = Encoding.ASCII.GetBytes("test");        // the data to be hashed
using (HashAlgorithm xxhash = XXHash32.Create())
{
  xxhash.TransformFinalBlock(input, 0, input.Length);
  byte[] result = xxhash.Hash;                         // retrieves the hash value.
}

NOTE: XXH64 is also supported: you can use xxHash64 class instead of xxHash32.
