Systems and methodologies are described that facilitate digital rights management in a wireless communication environment. Generally, content (e.g., data files, video images, etc.) can be downloaded and maintained in its encrypted state to ensure protection of digital rights. Consequently, programming applications that utilize such content decrypt the content at the time of use (e.g., playback or access). A file interface can be provided that allows applications to access encrypted content utilizing a standardized file I/O interface. Decryption of content can be transparent to individual applications utilizing encrypted content. Therefore, modifications cryptographic algorithms or procedures and changes in key sizes need not affect the programming applications.
