<mode>For AES-128 that means Hash1 is the key and Hash2 is the IV. For AES-256, the key is Hash1+Hash2 (concatenated, not added) and Hash3 is the IV. You need to strip off the leading Salted___ header, then use the salt to compute the key and IV. Then you'll have the pieces to feed into EVP_DecryptInit_ex.
