If you want to encrypt a personal photo for a friend, you might use PGP, which is a simple and convenient encryption method, but relies on a public and private key pair. Right-click on Encrypting File System and select Properties. For example, if you want to encrypt a confidential document for a client, you might use AES-256, which is a strong and secure encryption algorithm, but requires a complex and unique key. You should consider the following factors when choosing an encryption method: the sensitivity and confidentiality of your data, the legal and ethical obligations of your data, the trustworthiness and reliability of your recipient, and the encryption standards and protocols of your industry or sector. However, encryption can also increase the size of your files, make them incompatible with some programs or devices, or expose them to hackers or malware. Encryption can protect your files from unauthorized access, tampering, or theft.

Encryption is the process of transforming your files into unreadable codes that can only be decrypted with a key or a password.


Encryption methods are also diverse and have different pros and cons.
