File decryption is the process of converting encrypted data back into its original readable form using a decryption key or password. Encrypted files are protected from unauthorized access, and decryption ensures that only authorized users can access the content.

One common use case is securely retrieving sensitive business documents or personal files stored in encrypted cloud storage. Without the correct key, the data remains inaccessible, making encryption and decryption critical for cybersecurity, data privacy, and regulatory compliance.

File decryption is widely used in cloud storage, messaging apps, and cybersecurity protocols, ensuring data remains protected while allowing authorized access when needed.
