ZTools

Here there are two tiny C utilities to split ZIP archives like WinZip/PKZip (ZSplit) and to encrypt a ZIP archive with AES (ZAes).

ZSpan

Simply compile and do:

ZSpan source.zip KiB_segment destination_radix

ZAes

To compile the utility it is necessary to download elsewhere from the Internet the Dr. B. Gladman HMAC code or the openssl library, and the libtomcrypt (AES and SHA-1 code).

The code is given to Public Domain.
