Nonce is an important term used in cryptography, which stands for "number used once". It is essentially a random or unique number generated in order to keep information secure. In both public-key and symmetric-key cryptography, a nonce is used to prevent replay attacks, which occurs when an attacker intercepts and uses a previously sent message to gain access to a system.

Nonce values are typically generated by a random number generator. The nonce should be large enough to ensure that it is highly unlikely for it to be guessed.
