What encryption algorithm is used in DPAPI for WP7?

Question

Do someone of you know what encryption algorithm is used exactly in the Data Protection API for WP7?

I've read a few MSDN and Wikipedia articles on this, but most of them focussed on DPAPI for the pc versions of Windows. I could assume it is 3DES like it is said in this whitepaper, but I hope for AES. Between 2001 and 2011 a lot of things happened to cryptography :)

Any additional information whould be highly appreciated :)

Answer 1

As near as I can tell DPAPI continues to use the Triple-DES algorithm.

I can find no mention of it changing.

Answer 2

According to Passcape, DPAPI on Windows 7 by default uses the AES256 encryption in the CBC mode, SHA512 for hashing and PBKDF2 as password-based key derivation routine
