    It would be interesting, if it would be possible to create a self extracting file like with zip-control.
    Does anybody know, if files could be compressed, encrypted and be extracted with the zip-componets self-extracting method?

    Hi Dirk,

    You can create a self-extracting zip file that contains encrypted files. This is done by setting the EncryptionPassword property to the desired password when creating the self-extracting zip file. You can alos provide a different password for each file in the zip file via the ZipPreprocessingFile event.

    Keep in mind that the encryption algorithm used by the Xceed Zip Compression Library is the same one used by the PKZip 2.04g program.

    This type of encryption can resist attacks by amateurs if the password is well chosen and long enough (at least 16 characters) but it will probably not resist attacks by determined users or experts. Therefore, we suggest that you always use long passwords, and when possible, do not rely solely on this encryption system to protect sensitive data.

    The Xceed Zip Compression Library does not support AES encryption.
