What is the most secure way to encrypt a file?
Encryption options BitLocker is the preferred and most secure method, but it will not allow you easily to select and encrypt individual files and folders (you can do this by creating an encrypted file container using VHD.) Encrypting File System (EFS) is the alternative, but is not recommended for super-sensitive data.
How is encryption done?
Encryption uses complex mathematical algorithms and digital keys to encrypt data. An encryption algorithm (cipher) and an encryption key encode data into ciphertext. Once the ciphertext is transmitted to the recipient, the same or different key (cipher) is used to decode the ciphertext back into the original value.

What is encryption in cryptography?
Encryption in cryptography is a process by which a plain text or a piece of information is converted into ciphertext or a text which can only be decoded by the receiver for whom the information was intended . The algorithm that is used for the process of encryption is known as a cipher. It helps protect consumer information, emails, and other sensitive data from unauthorized access to it and secures communication networks. Presently there are many options to choose from and find the most secure algorithm which meets our requirements.
