TASK WORKFLOW

Free Security Tools Online

Handle common security utility tasks with clear warnings and browser-based helpers.

This workflow is built for developers, admins, students, and privacy-conscious users. It links only to FastTool pages that pass the current review-public quality gate, so every listed tool has a working interface, supporting content, and clear limits.

STEP 3

Hash Generator (SHA/MD5)

Generate MD5, SHA-1, SHA-256, SHA-384, SHA-512 hashes for text or files. HMAC mode, compare hashes, drag-and-drop file hashing, uppercase/lowercase toggle.

  • MD5, SHA-1, SHA-256, SHA-384, SHA-512 algorithms
  • Generate all hashes simultaneously
  • HMAC mode with secret key
Open Hash Generator (SHA/MD5)

STEP 4

JWT Decoder

Decode and inspect JWT tokens with color-coded header, payload, and signature sections. Check expiry status, verify HMAC-SHA256 signatures, and explore common JWT claims.

  • Auto-decode on paste/type
  • Color-coded JWT sections (header, payload, signature)
  • Token expiry status with human-readable dates
Open JWT Decoder

STEP 5

Base64 Encode/Decode

Encode and decode Base64 with text mode, file mode, image-to-Base64 data URI, Base64-to-image preview, URL-safe variant toggle, live conversion, character count, and download support.

  • bidirectional encode and decode toggle
  • text mode with live conversion as you type
  • file mode with drag-and-drop: encode and decode binary files
Open Base64 Encode/Decode

STEP 6

URL Encode/Decode

Encode and decode URLs with full URL parser showing protocol, host, path, query params, and fragment. Query string builder, bulk mode, encodeURI vs encodeURIComponent toggle, and live conversion.

  • bidirectional encode and decode with stats
  • full URL parser: protocol, host, path, query params, fragment with click-to-copy per component
  • query string builder with live URL generation and parameter count
Open URL Encode/Decode

STEP 7

Text Encrypt/Decrypt

Encrypt and decrypt text using AES-256-GCM via the Web Crypto API. Password-based key derivation with PBKDF2, auto-generate strong passwords, base64 output with visual lock/unlock indicator.

  • AES-256-GCM encryption via Web Crypto API
  • PBKDF2 key derivation (600k iterations)
  • Auto-generate strong password
Open Text Encrypt/Decrypt

STEP 8

CSP Header Generator

Generate Content-Security-Policy HTTP headers for your web app — configure default-src, script-src, style-src, img-src, font-src, and more.

  • all major CSP directives
  • HTML meta tag output
  • common source presets
Open CSP Header Generator

How to Use This Workflow

  1. Use generated test values instead of real credentials when experimenting.
  2. Check strength before storing or sharing a password policy.
  3. Decode tokens for structure, not for trusting unknown data.
  4. Review sensitive work inside your own approved environment when required.

Quality Notes

These workflow pages are generated from the same review-public tool list used by the sitemap, homepage, tool sidebars, and command palette. If a tool is policy-sensitive or needs a deeper manual audit during review, it is not promoted here.
