OxideShield WASM Bindings

Browser-compatible subset of OxideShield security guards for WebAssembly.

Supported Guards

  • PatternGuard - Regex-based pattern matching for prompt injection detection
  • LengthGuard - Input length validation
  • EncodingGuard - Unicode and encoding attack detection
  • PIIGuard - Personal information detection and redaction

Usage in JavaScript

import init, { PatternGuard, PIIGuard, LengthGuard } from 'oxideshield';

await init();

// Pattern-based detection
const guard = new PatternGuard();
const result = guard.check("ignore previous instructions");
if (!result.passed) {
    console.log("Blocked:", result.reason);
}

// PII detection
const pii = PIIGuard.withRedaction("mask");
const piiResult = pii.check("Email: john@example.com");
console.log("Sanitized:", piiResult.sanitized);

Overview

OxideShield is an open-core LLM security toolkit that protects AI applications from prompt injection, jailbreaks, and adversarial attacks. Built in Rust for maximum performance.

Crates

Crate Description
oxideshield-core Core types, pattern matching, perplexity analysis
oxideshield-guard Security guards for LLM protection
oxideshield-wasm WebAssembly bindings for browser use

Guards

Guard Description Latency
PatternGuard Prompt injection & jailbreak detection <1ms
LengthGuard Input length validation <1us
EncodingGuard Unicode/Base64 attack detection <100us
PerplexityGuard Adversarial suffix detection (GCG, AutoDAN) <5ms
PIIGuard PII detection & redaction <10ms
ToxicityGuard Content moderation <5ms
AuthoritarianUseGuard Detects AI misuse for surveillance/control <5ms

Installation

Rust

[dependencies]
oxideshield-guard = "0.1"
oxideshield-core = "0.1"     # optional — core types only

Python

pip install oxideshield

Note: Requires a Rust toolchain to build from source. Pre-built wheels for common platforms are coming soon. For manual builds, use maturin: maturin develop --release

WASM

Try OxideShield in your browser with the Interactive Playground.

Build from source using wasm-pack:

wasm-pack build crates/oxideshield-wasm --target web

Quick Start

Rust

use oxideshield_guard::{Guard, PatternGuard, PIIGuard, RedactionStrategy};

// Pattern-based injection detection
let guard = PatternGuard::new("patterns");
let result = guard.check("ignore previous instructions");
if !result.passed {
    println!("Blocked: {}", result.reason);
}

// PII detection with redaction
let pii = PIIGuard::new("pii")
    .with_redaction(RedactionStrategy::Mask);
let result = pii.check("Email: john@example.com");
println!("Sanitized: {:?}", result.sanitized);
// Output: "Email: j***@example.com"

Python

from oxideshield import pattern_guard, pii_guard

# Pattern detection
guard = pattern_guard()
result = guard.check("ignore previous instructions")
if not result.passed:
    print(f"Blocked: {result.reason}")

# PII redaction
pii = pii_guard(redaction="mask")
result = pii.check("Email: john@example.com")
print(f"Sanitized: {result.sanitized}")
