pii-shield-wasi 2.1.1

High-performance PII redaction scanner using Go WASM (WASI)

pii-shield-wasi

High-performance PII redaction scanner powered by a core Go engine compiled to WebAssembly (WASI). It provides lightning-fast text analysis with hybrid heuristic and entropy-based validation.

Installation

pip install pii-shield-wasi

Usage

from pii_shield import PiiShield, PiiShieldConfig

# Initialize the scanner with optional configuration overrides
shield = PiiShield(PiiShieldConfig(
    entropy_threshold=4.0,
    confidence_score=0.8
))

text = "Connecting to DB with password: MySuperSecretPassword123!"
redacted_text = shield.redact(text)

print(redacted_text)
# Output might redact the high entropy secret based on context

Features

• Blazing Fast: Runs a highly optimized Go WASM binary in a native V8/Wasmtime environment.
• Zero-Allocation: Hot-paths have been optimized to prevent garbage collection overhead during large log streaming.
• Hybrid Scoring: Combines static whitelists, regex heuristics, and Shannon entropy for zero false-positives on things like UUIDs and IPv6 addresses.
