Symmetric Encryption:

This is a form of encryption where a single key is used to both encrypt and decrypt the message.

This means that both the originator and the recipient of the message have to have the same key, and it has to have been shared securely between them if used to confidential messages, because anyone with the key can decrypt the ciphertext.

Attached are some code samples in Python and JavaScript. See this article for more:
