Adding a nonce to a form. To add a nonce to a form, call wp_nonce_field() specifying a string representing the action. By default wp_nonce_field() generates two hidden fields, one whose value is the nonce and one whose value is the current URL (the referrer), and it echoes the result. For example, this call:

the present, or immediate, occasion or purpose (usually used in the phrase for the nonce). 2. (of a word or phrase) coined and used only for a particular occasion: nonce forms such as “paintrix,” meaning “a female painter.”.

Securing Our Plugin with a Nonce. As mentioned earlier, there are two steps to the process: first, we need to create a nonce that will be submitted with our form. Second, we need to verify that nonce when the form is submitted. To create a nonce field in our form, we can use wp_nonce_field():

Cryptographic nonce. Typical client-server communication during a nonce-based authentication process including both a server nonce and a client nonce. In cryptography, a nonce is an arbitrary number that may only be used once. It is similar in spirit to a nonce word, hence the name. It is often a random or pseudo-random number issued in an authentication protocol to ensure that old communications cannot be reused in replay attacks.

We’ve learnt what a WordPress nonce is, and how WordPress uses nonces to prevent malicious CSRF attacks. By building a basic WordPress plugin, we’ve shown how a plugin – and WordPress – can potentially be exploited if nonces are not created and verified.

Golden Nonce. A golden nonce in Bitcoin mining is a nonce which results in a hash value lower than the target difficulty. In many practical mining applications, this is simplified to any nonce which has 32 leading zeroes, with a secondary test checking if the actual value is lower than the target difficulty.

Nonce Apostolique or Nuncio; the apostolic and diplomatic representation of the Holy See. Cryptographic nonce, a number or bit string used only once, in security engineering. Nonce (slang), a British and Australian slang term for a sex offender, usually a sexual abuser of children. Nonce word, a word used to meet a need that is not expected to recur. The Nonce, American rap duo.

A nonce is an arbitrary number used only once in a cryptographic communication, in the spirit of a nonce word. They are often random or pseudo-random numbers. Many nonces also include a timestamp to ensure exact timeliness, though this requires clock synchronization between organizations.

The nonce in a bitcoin block is a 32-bit (4-byte) field whose value is set so that the hash of the block will contain a run of leading zeros. The rest of the fields may not be changed, as they have a defined meaning. Any change to the block data (such as the nonce) will make the block hash completely different.
