Every tool you need. Zero friction.

All-in-one cryptography lab: detect encodings, auto-decode pipelines, hash, AES/ChaCha encrypt, JWT, certificates, RSA keys, and secure random — 100% in your browser.

Generate cryptographically secure passwords, API keys, salts, IVs, nonces, and UUIDs in your browser.

Convert between hex, text, binary, Base64, and more. Detect unknown hex strings automatically.

Compute SHA-1, SHA-256, and SHA-512 hashes in the browser.

Generate SHA-256 and dozens of other digests (SHA-3, BLAKE3, MD5, …). Verify and compare hashes locally.

Generate RSA-OAEP, RSA-PSS, ECDSA P-256, Ed25519, and X25519 key pairs. Export PEM. Encrypt with RSA-OAEP.

Decode JWT header and payload without verifying signatures.

Encode and decode Morse code instantly. Also detect Morse automatically in the Crypto Lab analyzer.

Apply ROT13, ROT5, ROT18, and ROT47 instantly. Classical cipher tools included.

Encrypt and decrypt Caesar cipher with custom shifts. Includes Vigenère, Atbash, Rail Fence, and more.

Generate MD5 checksums for legacy compatibility. Security warnings included — prefer SHA-256 for integrity.
