Encrypting File System (EFS) is used to encrypt files and folders. EFS is easy to use, with nothing more than a check box in a file's properties.
You need to first export the Encrypting File System (EFS) certificate and key on the computer where the files were encrypted, and then import them on the computer that you transferred the files to.
If you were to go by the definition cited by the NIST Computer Security Resource Center, an encryption certificate is: A certificate containing a public key that is used to encrypt electronic messages, files, documents, or data transmissions, or to establish or exchange a session key for these same purposes.”
Definition(s): A certificate containing a public key that can encrypt or decrypt electronic messages, files, documents, or data transmissions, or establish or exchange a session key for these same purposes.
File encryption works through the use of complex algorithms. An encrypted file is one that has had an encoding algorithm applied to it to scramble the data. The file becomes unreadable once scrambled, but the effect is only temporary. The encrypted data comes with a key the sender provides.
Moving an encrypted file to a non-NTFS partition removes the encryption. -Files remain encrypted and inaccessible even when the drive is moved to another computer or if another operating system is used. This is because the encryption keys needed to decrypt the file do not exist on these other systems.
If you have files and/or folders on your computer that contain sensitive information, it is a good idea to use encryption to keep this information from prying eyes. Encryption will also make it difficult, if not impossible, for hackers to access this data if it falls into the wrong hands.
Transfer the certificate file to the computer you want to open the encrypted file on and open the Certificate Manager on that computer. Open the "Personal" category, open the "Action" menu, move your cursor over "All Tasks" and select the "Import" option. Follow the prompts in the import wizard.
