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.

Calculate reaction velocity with Michaelis-Menten, estimate Km/Vmax via Lineweaver-Burk, and model enzyme inhibition.

Solve pressure, volume, temperature, or moles with the Ideal Gas Law (PV=nRT) or Combined Gas Law; also gas density and molar mass.

Convert text into every decorative Unicode style at once and compare them side-by-side — small caps, bold, italic, script, fraktur, double-struck, monospace, circled, fullwidth, strikethrough, underline, upside-down.
fancy-text-generatorSecurity
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).
entropy-calculatorAstronomy
Convert astronomical positions between equatorial (RA/Dec J2000 and B1950), galactic (l/b), and supergalactic (SGL/SGB) coordinate systems. Accurate J2000 IAU 1958 galactic rotation, de Vaucouleurs supergalactic system, and IAU 1976 precession between epochs. Accepts sexagesimal (12h51m26s) or decimal-degree input and shows all four systems for each object.
