WebIn cryptography a nonce may be used to prevent replay attacks, where the attacker captures and replays a previosuly used message. The two most important things to remember when using a nonce, especially with respect to ( CSP ), is that we only use our nonce once (for one request), and the nonce should be so random that no one could guess it.

"WebThe ChaCha20-Poly1305 algorithm as described in RFC 8439 [1] takes as input a 256-bit key and a 96-bit nonce to encrypt a plaintext, with a ciphertext expansion of 128-bit (the tag size). In the ChaCha20-Poly1305 construction, ChaCha20 is used in counter mode to derive a key stream that is XORed with the plaintext. " - Cryptographic nonce
