AES Encryption Tool
Encrypt and decrypt text using AES-256-GCM with PBKDF2 key derivation. 100% client-side using Web Crypto API.
Bcrypt Generator
Generate bcrypt-style password hashes with configurable cost rounds. Uses SHA-256 simulation client-side.
Hash Generator
Generate SHA-1, SHA-256, SHA-384 and SHA-512 cryptographic hashes instantly using the browser's Web Crypto API.
HMAC Generator
Generate HMAC (Hash-based Message Authentication Code) using SHA-256 or SHA-512. Client-side using Web Crypto API.
JWT Decoder
Decode and inspect JWT tokens. View header, payload and signature without verification. 100% client-side.
JWT Encoder
Create JWT tokens with custom header and payload. Generate HS256 signed tokens client-side.
MD5 Generator
Generate MD5 hashes from any text input. Pure client-side — nothing is sent to a server. Supports uppercase output and live hashing.
Nonce Generator
Generate cryptographic nonces for security protocols
Password Generator
Generate cryptographically strong, random passwords instantly in your browser. No data ever leaves your device.
Password Policy Validator
Validate passwords against custom policy rules
Password Strength Checker
Check password strength with entropy calculation, crack time estimate and detailed checklist.
Random Password List Generator
Generate a list of secure random passwords. Customize length, character sets, and count. Cryptographically secure using Web Crypto API.
Random Token Generator
Generate cryptographically secure random tokens in Hex, Alphanumeric, Base64URL, UUID and more formats.
RSA Key Generator
Generate RSA public/private key pairs in the browser
Secure Password Generator
Generate cryptographically secure passwords with custom character sets, length and strength indicator.
SHA-1 Generator
Generate SHA-1 hashes instantly. Uses Web Crypto API — 100% client-side. ⚠️ SHA-1 is cryptographically broken — use SHA-256 or SHA-512 for security.
SHA-256 Generator
Generate SHA-256 hashes instantly. Uses Web Crypto API — 100% client-side.
SSL Certificate Decoder
Decode and inspect SSL/TLS certificate details
URL Safety Checker
Check if a URL is safe to visit using security heuristics
