What is decryption?

Decryption refers to the process of converting encoded data back into a readable format. In the context of information security, encryption is used to protect data by converting it into a coded format that can only be accessed by those who possess the correct decryption key or password. Once the data is decrypted, it returns to its original, readable state, allowing authorized users to access and understand the information. This is a critical process in maintaining data security, especially when it involves sensitive information protected under regulations like HIPAA.

The other answers do not accurately capture the concept of decryption. For instance, encoding data and storing data securely are important processes within the realm of data management and security, but they do not specifically define decryption.
