🛡️ 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.
