WebChaCha20 and XChaCha20¶ ChaCha20 is a stream cipher designed by Daniel J. Bernstein. The secret key is 256 bits long (32 bytes). The cipher requires a nonce, which must not be reused across encryptions performed with the same key. There are three variants, defined by the length of the nonce: WebJul 9, 2024 · The ChaCha20 stream cipher. ChaCha is a stream cipher family created by Daniel J. Bernstein.
