ChaCha20 Encrypt then Hex

ChaCha20 is a fast stream cipher used in TLS. Hex encoding makes ciphertext storable.

What it solves

ChaCha20 encrypt then hex-encode the ciphertext.

Input → Output

ChaCha20 Encryptor input → Hex Encoder output across 2 steps.

Before you start

  • Plaintext and ChaCha20 key

The pipeline

  1. 1 ChaCha20 Encryptor chacha20-encrypt

    Encrypt text with the ChaCha20 stream cipher (RFC 8439) — a real algorithm verified byte-for-byte against official RFC test vectors. 256-bit key (32 bytes), 96-bit nonce (12 bytes), 32-bit block counter. Free, private, and 100% client-side. Never reuse a nonce with the same key.

    Params: key=0123456789abcdef0123456789abcdef, nonce=0123456789ab

  2. 2 Hex Encoder hex-encode

    Encode text to hexadecimal online. Free, private, and 100% client-side.

TUTORIAL
How to Chain Encoding and Hashing Workflows
Real data-processing tasks rarely use a single tool. This tutorial shows how to compose encoding and hashing tools into multi-step pipelines: a base64-to-hash-to-hex verification chain, parallel multi-algorithm integrity checking, and an automatic encoding-format conversion chain. Each pattern maps to an existing workflow recipe (base64-encode-decode-verify, hmac-sign-verify) and explains when to use inline tool chaining versus a saved recipe.
