Client libraries

Promise-based, with TypeScript types. Works with require and import.

npm install https://rdrand.com/Downloads/jebtek-rdrand-2.0.0.tgz

const { RdRand } = require("@jebtek/rdrand");
const rng = new RdRand();
await rng.generateKey(32);     // "kq9ZLx0t…"
await rng.generateBytes(16);   // Buffer
await rng.generateUInt();      // 0 to 2147483647
rng.source;                    // "rdrand", "rndr" or "service"

One jar with the hardware library for every platform inside. Blocking calls that take microseconds on hardware.

implementation(files("libs/rdrand-kotlin-2.0.0.jar"))

import com.jebtek.rdrand.RdRand

val rng = RdRand()
rng.generateKey(32)
rng.generateBytes(16)          // ByteArray
rng.generateUInt()             // 0 to Int.MAX_VALUE
rng.source                     // RDRAND, RNDR or SERVICE

RDRAND and RNDR built in. The API fallback is the default service feature; turn it off for a dependency-free, hardware-only crate.

rdrand-client = { path = "rdrand-client-2.0.0" }   # Cargo.toml, after unzipping

let rng = rdrand_client::Client::new();
rng.generate_key(32)?;
rng.generate_bytes(16)?;       // Vec<u8>
rng.generate_uint()?;          // 0 ..= 2^31 - 1
rng.source();                  // Source::Rdrand, Rndr or Service

For .NET 6/8/9+ and .NET Framework 4.6.1+. Async and blocking methods.

dotnet add package JebteK.RdRand --version 2.0.0 --source <folder with the .nupkg>

using JebteK.RdRand;

using var rng = new RdRandClient();
await rng.GenerateKeyAsync(32);
await rng.GenerateBytesAsync(16);   // byte[]
await rng.GenerateUIntAsync();      // 0 to 2147483647
rng.Source;                         // Rdrand, Rndr or Service
