Client-Side Cryptographic Toolkit
A comprehensive, client-side cryptographic toolkit. All encryption, hashing, and encoding operations are performed entirely in your browser using the Web Crypto API â no data ever leaves your device.
This tool supports AES encryption (CBC, GCM, CTR modes) with 256-bit keys derived via PBKDF2 with 100,000 iterations, SHA-family hashing algorithms, Base64 encoding/decoding, and cryptographically secure password generation using the browser's CSPRNG.
All operations run in your browser. No server communication. Zero data retention.
Uses native browser cryptography for maximum performance and security.
Military-grade encryption with PBKDF2 key derivation and random IVs.
Built on established cryptographic standards and best practices.
