When using Password=password to encrypt a database, the encryption algorithm is RC4 (crypt.c line 249):

CryptDeriveKey(g_hProvider, CALG_RC4, hHash, 0, &hKey);

Is there some reason this couldn't be updated to be a stronger algorithm such as AES265?  I've made code changes in my own build using CALG_AES_256 which works fine.

Understandably this would have to go in as another option to allow existing databases encrypted with RC4 to be opened, but it would make a valuable addition.

I have submitted a patch to which addresses this issue by providing additional encryption algorithms but also maintaining compatibility to the RC4 encryption a little more than a week ago and am now awaiting some feedback.
