Welcome to DevSec Pro v1.0.1: • Zero-Permission architecture: No network access requested. • Offline JWT Signature Verification (HS256, RS256, ES256). • Hardware-isolated AES-256-GCM encrypted secret vault. • Unlimited bulk generation & exports for UUID v4, NanoID, Hex. • Smart Decoder, Cryptographic Hashes & X.509 Inspector.
Zero permissions, 100% offline: JWT verification, AES-256 vault & crypto suite
🛡️ DevSec Pro is the zero-permission, client-side cryptographic workbench engineered for software engineers, penetration testers, and backend architects who demand absolute privacy. Built on a zero-telemetry architecture, DevSec Pro operates completely air-gapped from the network. Your sensitive production secrets, cryptographic tokens, and authentication payloads never touch external servers or the cloud. 🔒 100% CLIENT-SIDE AIR-GAP: • 🚫 Zero Permissions: No internet access (android.permission.INTERNET is completely stripped). • 🛡️ Zero Tracking: No ads, no analytics, no third-party SDKs, and zero crash trackers. • ⚡ Local Execution: All cryptographic operations execute within your device's protected memory buffer. ━━━━━━━━━━━━━━━━━━━━━━━━━━ ✨ EXCLUSIVE PRO CAPABILITIES ━━━━━━━━━━━━━━━━━━━━━━━━━━ 1. 🔐 OFFLINE SIGNATURE VERIFICATION Inspect, decode, and cryptographically verify JSON Web Tokens (JWT) directly on-device: • Symmetric Algorithms: Verify HMAC signatures (HS256, HS384, HS512) with raw secret keys. • Asymmetric Algorithms: Verify digital signatures using standard PEM public keys (RS256, RS384, RS512, ES256, ES384, ES512). • Full claims dissection: Real-time validation for iat, exp, and nbf timestamps with human-readable epoch conversions. 2. 🗄️ AES-256-GCM ENCRYPTED VAULT A hardened local safe for sensitive development environment variables and infrastructure keys: • Military-Grade Encryption: Authenticated AES-256-GCM cipher with unique per-entry initialization vectors (IV). • High-Entropy KDF: Master password hardened via PBKDF2-HMAC-SHA256 with high iteration counts and cryptographic salt. • Hardware-Isolated Storage: Store production API tokens, database connection URIs, and server credentials securely offline. 3. ⚡ UNLIMITED BULK TOKEN GENERATION Generate enterprise-grade unique identifiers and random secrets with zero limits: • UUID v4, NanoID, and cryptographically secure random Hex bytes. • Batch Generation: Instantly create and export batches of 100 to 1,000 keys in a single tap—no cooldowns, no rewarded passes, no timeouts. ━━━━━━━━━━━━━━━━━━━━━━━━━━ 🛠️ CORE CRYPTO & DECODER WORKBENCH ━━━━━━━━━━━━━━━━━━━━━━━━━━ • 🔄 Multi-Format Smart Decoder: Bidirectional encoding/decoding for Base64, Base64URL, Hexadecimal (Base16), URL percent-encoding, and HTML entities. • ⚡ Cryptographic Hashes & HMAC: Compute MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, and keyed HMAC digests. • 📜 X.509 Certificate Inspector: Parse PEM public keys (RSA/EC) and X.509 certificates to extract Issuer DNs, subject info, and validity windows. • ⏱️ Clipboard Auto-Wipe: Automatic memory sanitation cleanses sensitive copied tokens from your Android clipboard after 60 seconds. Clean, high-performance architecture built for professional developers who refuse to compromise on security. Developed by LKPixel. Support & Security Contact: contact@lkpixel.com
