A nonce is a “Number used ONCE” that is typically randomly generated. A salt is a form of nonce, as is an initialization vector. The purpose of a nonce in hashing or encryption is to add more randomization to the hash or cipher text. A nonce is commonly shared between sender and recipient, and as its name implies, it is only used once. If everyone in your organization starting using the same password, for example, the stored salted hash for each would be different because each hashing of the password used a different nonce for the salting process. Their are other uses for a nonce, including within a cryptographic cipher.

This video was excellent, very helpful. Thank you
Thank you Sir. Hats of for your efforts.
Thank you for the series!
My pleasure!
Is salting hashed passwords somewhat similar to a nonce used during encryption?
