Abstract:
1. A method for encrypted file access comprising: an access program module, connected to at least one file system, intercepting a data request for accessing a plaintext file with information stored physically and consecutively on a hard disk and having a pre-determined order and length expected by a program that sends the data request, wherein the plaintext file includes a plaintext record having a key field and a plaintext data field; the access program module determining an encrypted file, associated with the plaintext file, based on a configuration file and the data request, wherein the configuration file indicates the encrypted file associated with the plaintext file and the encrypted file includes an encrypted record associated with the plaintext record, and wherein the encrypted record includes a header field, the key field, and an encrypted data field that is associated with the plaintext data field; the access program module determining one or more encryption keys based on the configuration file; and the access program module accessing the encrypted data field based on the one or more encryption keys and the key field, wherein accessing the encrypted data field based on the one or more encryption keys and the key field comprises:
