À propos de l'application

DevSec Toolkit is an offline developer utility engineered for security engineers, backend architects, and software developers. Inspect authentication tokens, calculate cryptographic digests, and decode data formats directly on your Android device without telemetry or data leakage.

Every transformation, hashing routine, and decoding step runs client-side. Your sensitive tokens and cryptographic secrets never leave your memory buffer.

KEY DEVELOPER UTILITIES:

1. JWT INSPECTOR & TOKEN DECODER
• Instant JSON Web Token (JWT) inspection: Decode headers, claims, and payload bodies.
• Formatted JSON display with syntax highlighting.
• Automated UNIX epoch conversion for issued-at (iat), expiration (exp), and not-before (nbf) timestamps with live token validity status.

2. MULTI-FORMAT SMART DECODER
• Auto-detect and parse arbitrary data payloads instantly.
• Bi-directional conversions: Base64, Base64URL, Hexadecimal (Base16), URL Percent-Encoding, and HTML entities.
• Clean, one-tap copy and inspection workflows for developer diagnostics.

3. CRYPTOGRAPHIC HASH CALCULATOR
• Calculate one-way hashing digests offline.
• Algorithms supported: MD5, SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512.
• HMAC Generation: Compute keyed-hash message authentication codes (HMAC-SHA256, HMAC-SHA512) for webhook validation and API signature verification.

4. CRYPTOGRAPHIC ID & SECRET GENERATOR
• Generate cryptographically secure UUID v4 identifiers.
• High-entropy NanoID and custom alphanumeric secrets generation.
• Secure random Hex bytes for session keys, salts, and environment variables.
• Rewarded Pass: Watch a short ad to unlock 30-minute unlimited bulk batch generation and multi-format exports.

5. X.509 CERTIFICATE & KEY INSPECTOR
• Inspect PEM-encoded X.509 Public Key Certificates and SubjectPublicKeyInfo (SPKI) files.
• Parse Subject Distinguished Names (DN), Issuers, Validity ranges, and Serial Numbers.
• Identify RSA modulus/exponent bit-lengths and Elliptic Curve (EC) named curves offline.

6. CLIPBOARD SANITIZATION
• Configurable Auto-Wipe clipboard timer: Automatically purges sensitive copied tokens, keys, and credentials from your device's clipboard after 60 seconds.

ENGINEERED FOR MODERN DEVELOPERS:
DevSec Toolkit is designed to be lightweight, responsive, and distraction-free. Whether you are debugging microservices, verifying authentication payloads, or handling system integration tasks, DevSec delivers the core cryptographic toolkit right to your pocket.
