What is the purpose of encryption?

Encryption - Wikipedia

The purpose of encryption is to ensure confidentiality by transforming information so that, ideally, only authorized parties can decode it. This process converts the original data, known as plaintext, into an alternative form known as ciphertext, thereby denying intelligible content to potential interceptors[1]. Additionally, encryption protects sensitive data, such as passwords and personal communications, from being exposed during transfer over the Internet[1].
