Security

Env File Secret Rotation Planner

Paste a .env file and get a staged secret-rotation plan. Detects database URLs, API keys, auth tokens, private keys, cloud credentials, payment keys and encryption secrets, scores each by exposure and age, and schedules them across a 4-week rotation timeline with a dual-key checklist and a generated .env.example. Optional last-rotated dates and a configurable cadence (30/90/180/365 days) drive compliance scoring.

Security

Digital Signature Generator

Sign a message with a private key or verify a signature with a public key — supports RSA-PSS (SHA-256), ECDSA (P-256), and Ed25519. Pure client-side crypto (Node crypto.createSign/createVerify), no network. Paste a PEM key to sign or to verify a base64 signature. This tool signs/verifies; it does not generate key pairs.

Security

Entropy Calculator

Measure the randomness of any data — Shannon entropy (bits/symbol), Min-Entropy (worst-case guess work), alphabet size, duplicate rate, and an average brute-force cracking time at a chosen hash rate. Rates data as Strong (≥128-bit min-entropy), Medium (64-127), or Weak (<64).
