Users only have access to the specific documents for which they have a key.
This has several advantages over FDE or Encrypted Partitions.ĭocument encryption gives you fine control over who has access to which documents. Ideally, every file will be encrypted with a unique key.

How to encrypt files with SecureDoc How To Encrypt Individual Files With Document Encryptionĭocument encryption (more properly file-level encryption) involves encrypting each document before it is saved. Sending a document to another computer by email, or even to an unencrypted disk on the same computer will leave the document unencrypted at its destination.

Reading and writing the encrypted disk is transparent to software once the disk is unlocked.įinally, remember that FDE only protects files while they are stored on the encrypted disk. Some sort of key management system is almost mandatory to avoid eventual data loss.Īnother weakness is that the system is vulnerable to hostile software while it is running. This makes the loss of the key much more damaging than when each document is encrypted individually with its own key. Perhaps most important, if the key is lost, the entire disk becomes unreadable. Since the encryption is automatically applied to everything on the disk, you can’t forget to encrypt something, and the encrypted data can’t appear in an unencrypted file on the disk. It provides a basic level of protection with little or no performance impact once the disk is encrypted. It is also possible for data stored in an Encrypted Partition to simultaneously appear in unencrypted form in a cache or swap file elsewhere on the disk. The necessity to decide whether or not each file belongs on an Encrypted Partition means there is a chance that the user will make a mistake and leave sensitive data exposed. The user must take care to store documents and other files in the proper partitions. In a system using Encrypted Partitions, data automatically gets encrypted/decrypted only when it is stored on an Encrypted Partition. And since the entire disk is encrypted, there is no way that sensitive data can find its way to an unencrypted file on the disk. Since the data on the disk is always encrypted, it is always inaccessible to anyone without the proper key, even if they physically take possession of the disk. Likewise, whenever data is written to disk, it is encrypted. Whenever data is read from the disk, it is decrypted before being used. When a user starts the system, they enter the encryption key, and the encryption software uses the key to encrypt/decrypt data on the fly. In a system using FDE, all the data on the disk is encrypted. When only parts of the disk are encrypted, you have Encrypted Partitions on the disk.

When you encrypt the entire disk, it is known as Full Disk Encryption (FDE). How To Encrypt Files With Disk Encryption?ĭisk encryption works by encrypting part or all of a disk drive or other storage device. We’ll take a quick look at how each type of encryption works, and talk about when you would want to use each type.

To read the document, you need to know a password or a secret key.
To read any data on the disk, you need to know a password or a secret key.
