A privacy-first suite of high-performance developer tools for cryptography, encoding, and identifier generation. All operations (SHA, Keccak, AES, ChaCha20, RSA, post-quantum ML-KEM, HMAC, Base64, and UUID v7) run 100% locally in your browser sandbox using the Web Crypto API and WebAssembly.
Cryptographic hashes & fast checksums: SHA-256, SHA-512, MD5, SHA-3, Keccak-256 (Ethereum), BLAKE2b/s, GOST R 34.11-2012 Streebog, xxHash32, MurmurHash2/3, CRC-32/64, Adler-32, and Whirlpool.
Symmetric & asymmetric cryptography: AES (128–512 bit GCM), ChaCha20, Twofish, Blowfish, Serpent, 3DES, DES, IDEA, Camellia, ARIA, RSA-2048 (OAEP), ECDSA (P-256), ECDH, Diffie-Hellman, and NIST FIPS 203/204 Post-Quantum (ML-KEM & ML-DSA).
Keyed message authentication: HMAC-SHA256 (JWT HS256, AWS SigV4), HMAC-SHA512, HMAC-SHA3, HMAC-BLAKE2, HMAC-Streebog GOST, Chinese HMAC-SM3 standard, HMAC-Whirlpool, HMAC-MD5, and HMAC-RIPEMD.
Password hashing KDFs and authentication schemes: Argon2id, bcrypt, scrypt, PBKDF2 (HMAC-SHA256/512), SHA-crypt, MD5crypt, Apache MD5, phpass, NTLM, SCRAM-SHA-256, CRAM-SHA-1, and MySQL authentication.
Instant data conversion & inspection: Base64, URL-safe Base64, Base32 (TOTP), clean Hex dumps, URL percent encoding, HTML entities, ROT13 cipher, raw Binary bits, and decimal ASCII.
Random UUID v4, time-ordered UUID v7 (RFC 9562), deterministic v3/v5, Minecraft offline player UUIDs, plus deep inspector for timestamps, clock sequences, and MAC node bytes.
Word and character counting, find & replace with regex support, case conversion, and text cleanup.
No. All hash computations, encryption, key generation, and encoding routines are executed strictly client-side inside your browser sandbox via native hardware Web Crypto API instructions and WebAssembly. You can inspect the Network tab in DevTools — zero payload bytes leave your machine.
Yes. Once the web application is loaded in your browser, all cryptographic calculators, encoders, and generators function completely offline.
Every algorithm strictly follows formal NIST FIPS, IETF RFC, and ISO standards. Generated outputs are fully interoperable with OpenSSL, Java JCE, Python (cryptography), Go, and Node.js.
All operations run locally in your browser.
