> A message authentication code (MAC) is produced from a message and a secret key by a MAC algorithm.
> A MAC of the same message produced by a different key looks unrelated. Even knowing the MAC of other messages does not help in computing the MAC of a new message.

> An HMAC is a MAC which is based on a hash function. The basic idea is to concatenate the key and the message, and hash them together.

> A MAC is a **signature** based on a secret key, providing similar assurances to a signature scheme based on public-key cryptography such as RSA-based schemes where the signature must have been produced by a principal in possession of the private key.

npm package: @plugin.land/generate-nonce
Description: > Yes, a nonce is a number not used more than once. In its purest sense there should be no other requirements than this, i.e. randomness or unpredictability should not be necessary.

The nonce generated here is a random number.

- Avoid using child_process.exec, and never use it if the command contains any input that changes based on user input.
- Try to avoid letting users pass in options to commands if possible. Typically values are okay when using spawn or execfile, but selecting options via a user controlled string is a bad idea.
- If you must allow for user controlled options, look at the options for the command extensively, determine which options are safe, and whitelist only those options.
