Encode, hash, encrypt, sign — Base64, SHA, bcrypt, Argon2, AES-GCM, RSA, ECDSA — all in-browser.

Privacy: every bit of crypto happens inside your browser — nothing is sent to a server. Web Crypto handles AES / RSA / ECDSA / HMAC / PBKDF2 natively; MD5, SHA-3, bcrypt, Argon2id, scrypt and Blake2b load on demand from hash-wasm.
