What is file encryption and how does it work on a Mac?
File encryption is a process of converting plaintext data into unreadable ciphertext to protect it from unauthorized access. On a Mac, file encryption is achieved through various methods, including the use of passwords, keys, or certificates. When a file is encrypted, its contents are scrambled, making it impossible for anyone without the decryption key or password to access the data. This ensures that even if the file is intercepted or accessed by an unauthorized party, the data will remain secure.
The encryption process on a Mac typically involves the use of algorithms, such as AES (Advanced Encryption Standard), which is a widely accepted and secure encryption standard. When a user encrypts a file, the algorithm uses the provided password or key to generate a unique encryption key, which is then used to scramble the data. To decrypt the file, the same password or key is required, which is then used to generate the decryption key, allowing the user to access the original plaintext data. This process ensures that the data remains secure and can only be accessed by authorized individuals.
Why do I need to unencrypt files on my Mac, and what are the benefits?
