Iscc.Lib

CI NuGet License

High-performance C# / .NET bindings for ISO 24138:2024 — International Standard Content Code (ISCC). Built as P/Invoke bindings to the Rust-compiled ISCC library via csbindgen, with an idiomatic C# API featuring typed result records, IDisposable streaming hashers, and PascalCase method names.

What is ISCC

The ISCC is a similarity-preserving fingerprint and identifier for digital media assets. ISCCs are generated algorithmically from digital content, just like cryptographic hashes. However, instead of using a single cryptographic hash function to identify data only, the ISCC uses various algorithms to create a composite identifier that exhibits similarity-preserving properties (soft hash).

Installation

dotnet add package Iscc.Lib

Quick Start

using Iscc.Lib;

// Generate a Meta-Code from content metadata
var result = IsccLib.GenMetaCodeV0("Hello World");
Console.WriteLine(result.Iscc); // "ISCC:..."

// Streaming for large files
using var hasher = new IsccDataHasher();
using var fs = File.OpenRead("large_file.bin");
byte[] buf = new byte[65536];
int n;
while ((n = fs.Read(buf, 0, buf.Length)) > 0)
    hasher.Update(buf.AsSpan(0, n));
DataCodeResult dataResult = hasher.Finalize();
Console.WriteLine(dataResult.Iscc);
