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: WebXChaCha 20 est une formule de sécurité symétrique, ce qui indique qu'elle utilise une seule clé pour sécuriser ainsi que décrypter les informations. De plus, comme elle chiffre chaque bit d'information séparément, elle est …
WebJul 17, 2024 · ChaCha20 is also used by many well-known protocols, such as TLS 1.3. The larger nonce size doesn't necessarily matter for security; it depends on the application … WebCaution. This encryption is unauthenticated, and does not prevent chosen-ciphertext attacks. Make sure to combine the ciphertext with a Message Authentication Code, for example with sodium_crypto_aead_xchacha20poly1305_ietf_encrypt() function, or sodium_crypto_auth().
