System.IO.Hashing 9.0.0-rc.1.24431.7
About
System.IO.Hashing offers a variety of hash code algorithms.
Hash code algorithms are pivotal for generating unique values for objects based on their content, facilitating object comparisons, and detecting content alterations. The namespace encompasses algorithms like CRC-32, CRC-64, xxHash3, xxHash32, xxHash64, and xxHash128, all engineered for swift and efficient hash code generation, with xxHash being an "Extremely fast hash algorithm".
Warning: The hash functions provided by System.IO.Hashing are not suitable for security purposes such as handling passwords or verifying untrusted content. For such security-critical applications, consider using cryptographic hash functions provided by the System.Security.Cryptography namespace.
Key Features
- Variety of hash code algorithms including CRC-32, CRC-64, xxHash3, xxHash32, xxHash64, and xxHash128.
- Implementations of CRC-32 and CRC-64 algorithms, as used in IEEE 802.3, and described in ECMA-182, Annex B respectively.
- Implementations of XxHash32 for generating 32-bit hashes, XxHash3 and XxHash64 for generating 64-bit hashes, and xxHash128 for generating 128-bit hashes.
How to Use
Creating hash codes is straightforward.
Call the Hash
method with the content to be hashed.
Here is a practical example:
using System;
using System.IO.Hashing;
byte[] data = new byte[] { 1, 2, 3, 4 };
byte[] crc32Value = Crc32.Hash(data);
Console.WriteLine($"CRC-32 Hash: {BitConverter.ToString(crc32Value)}");
// CRC-32 Hash: CD-FB-3C-B6
byte[] crc64Value = Crc64.Hash(data);
Console.WriteLine($"CRC-64 Hash: {BitConverter.ToString(crc64Value)}");
// CRC-64 Hash: 58-8D-5A-D4-2A-70-1D-B2
byte[] xxHash3Value = XxHash3.Hash(data);
Console.WriteLine($"XxHash3 Hash: {BitConverter.ToString(xxHash3Value)}");
// XxHash3 Hash: 98-8B-7B-90-33-AC-46-22
byte[] xxHash32Value = XxHash32.Hash(data);
Console.WriteLine($"XxHash32 Hash: {BitConverter.ToString(xxHash32Value)}");
// XxHash32 Hash: FE-96-D1-9C
byte[] xxHash64Value = XxHash64.Hash(data);
Console.WriteLine($"XxHash64 Hash: {BitConverter.ToString(xxHash64Value)}");
// XxHash64 Hash: 54-26-20-E3-A2-A9-2E-D1
byte[] xxHash128Value = XxHash128.Hash(data);
Console.WriteLine($"XxHash128 Hash: {BitConverter.ToString(xxHash128Value)}");
// XxHash128 Hash: 49-A0-48-99-59-7A-35-67-53-76-53-A0-D9-95-5B-86
