Re: Zipping files woes and evils. :)

Hi Jason,

If you're supplying a password, I assume this means you need to use the
cryptography support in .ZIP. (Most people do not use passwords on a
.ZIP file, which might be why this seems extra difficult for you, it's
less mainstream.)

It's been a few years since I've done this, but when I did I found 3
tools that supported passwords:

1. InfoZip. Works well, but only supported older encryption standards
(not sure if this has changed since I looked into it.)

2. 7-Zip. Did support the latest cryptography, and worked well. A bit
more complicated because it supports tons of different formats, not just
ZIP.

3. The PKWARE commercial offering. I didn't look into this any further
beyond determining that it supported passwords, and never tried it myself.

Other tools out there, such as the MiniZip/ZLIB tool and JAR did not
support passwords or encryption when I looked into it.

Both InfoZip and 7-Zip run in PASE.

I used to use the zip utility from here,

http://uzaemon.d.dooo.jp/#download

to zip and unzip .zip files on IBM i. However, that product has not been
updated to the latest ZLIB in a long period of time. So when I noticed

that

IBM gave us the CPYTOARCF commands I was happy, but you can't supply

that a

password. And, you always get the full directory path in the .zip and

there

isn't a way to stop that that I know of.

So what do others do for their .zip files? Do you use a commerical

product

or are you using ZLIB with minizip included? Are you building your own?

I'd

love to know as I hate using 3rd party apps if I don't have to.


Thanks,
