Please find a quick recap of the current status. Let me know whether this helps.

*	The AES-256 encryption is in CBC mode.
*	A default initialization vector with a block of all 0x00 bytes (i.e. 16 bytes of zeros) can be used, and has the same effect as if no IV was being used. 
*	The key is the SHA-256 of the passphrase Unicode string. The NULL terminator is excluded from the passphrase string. 
*	The encryption scheme uses PKCS7 block padding.
