Abstract
A method for encrypting a file using a combination of an electronic device and a protection communication-enabled (PCE) wireless device is provided. The method includes using an encryption/decryption engine executing on the electronic device to encrypt a first flag string, which is a binary string stored in a header of the file, with a digest value to create an encrypted flag string. The digest value is associated with the PCE wireless device, which is a device having a transmission application program installed thereon for enabling interaction between the PCE wireless device and the encryption/decryption engine. The method also includes encrypting at least a portion of the file using the digest value and a first password provided by a user, thereby generating an encrypted file that includes an encrypted version of at least a portion of the file, the encrypted flag string, and the first flag string.
