I'd like to compress and encrypt in AES-256 winzip mode: nowadays it is possibile -if i'm not wrong- to compress and encrpt with the standard winzip encryption schema, that isn't very secure.....
AFAIK, there is only one (commercial) product that does it...

    So... If there's only a commercial product that does that, and WinZip does not open the code or ship some API's there's nothing to do yet...

    Hi, when I said that there is only one product that does it I was referring to mac world: in windows world I know IZArc (freeware), but probably there are more.
    About the specification of WinZip, I am not a programmer so I cannot evalueate them, but on their web site there is something that looks like: http://www.winzip.com/aes_info.htm

    Hi,
    I was partially wrong: p7zip support the AES *encryption*: for example:
    7z a -tzip archive.zip FILETOARCHIVE.txt -mem=AES256 -psecret
    The point is probably to let that in Keka the user chooses the encryption method, because the default is ZipCrypto and not AES.
    Note that the AES *decryption* already works.

    Hi again Marco,

    Sure I've to implement a combo box to choose encryption algorithm and one for compression algorithm too. Hope to do it for the next release.

    Matter of time :)

    The AES encryption scheme used by WinZip is documented on their website:
