Dear VS1010 users,
Here is demonstration solution for software decryption. The attached solution provides demonstration code for software decryption for two scenarios.
1) Playing encrypted media content
2) Accessing encrypted files through normal file operations (fopen, fread, fclose)
Solution has three projects: decplay for content playing, decrypt for device decryption and dectest project for testing decplay and decrypt projects and for a starting point for the usage of the decryption features in your own software.
The cipher in this demonstration code has no cryptographic strength.
The sd_card directory has encrypted files for dectest test software.
