Extract from .msi without Windows Installer

?

??

Hi,

I don't have Windows Installer, but I need to extract files from .MSI
and .MSP.

Is there a freeware that can do it?

TIA.

Why, when the Windows Installer package is available from soooo many
places. (I updated mine to msi spec from the cd on the cover of a PC
magazine)
And I`m pretty sure it is available as a download from the Microsoft
site.

I only want to extract some files, but not to install a huge package.

7Zip can open some (but not all) .MSI files

I tried 7Zip with an .MSI archive and an .MSP archive. Yes, 7Zip does
successfully extract files from those two archives, and very fast.

Played 7zip for an hour. It's truly great. But the button for expanding
the drop-down list of folder history does not work. And I hope it will
support, via the context menu as Winzip 8.0 does, simutaneouly
extracting from multiple archives selected from WinExplorer.

I haven't tried it, but the msi2xml project "disassembles" msis down
to components - not sure if that is going to allow you extract the
files you need though.

XML is beyond me. But I do appreciate your help. This house is warm.

that would be a nice feature - but what impressed me most about 7z was the
256 bit AES encryption for self-extracting archives. More recent payware
archivers like winzip have decent crypto (as opposed to the bad joke that
was the password protection on original pkzip) but AFAIK this is the only
decent free compressor/encryptor at 256 bit.

Be aware, 256 encryption has been cracked, the same as 128 was.
They are working on a better one though.

interesting. Can you give me links?
most serious cryptographers still believe 128 bit symmetric encryption (eg
IDEA or CAST) is secure.

Really? I must have dozed off or something for the past 3 years. I
use 256-bit Blowfish encryption, for symmetric encryption, and
2048-bit Diffie-Hellman for public key just because I can. For
symmetric key encryption (one key used) we are not going need go too
much further than 128-bit very soon. As long as adequate algorithms
such as factoring large primes ala RSA are used (called "hard
problems") by mathemeticians, you have to resort to brute force
cracking; i.e., trying all possible combinations that the key might be
composed of.

According to testimony in 1997 by William Crowell, Deputy director of
the NSA, if all 260 million computers in the world (at that time) were
applied to brute force 128-bit single key decryption, it would take an
estimated 12 million times the age of the universe to break it.
Admittedly, that was 6 years ago. The authors of the paper also
stated, based on Moore's law of processing power doubling every 18
months, in 84 years we'd have that key broken in only a year's time.
Here's the link for that reference:

Cryptography, breaking keys & codes, will be the killer app for
quantum computing. A capable quantum computer probably won't be ready
for a few decades yet. George Johnson in his new book "A Shortcut in
Time: The Path to a Quantum Computer" stated that the conventional
computing power required to equal a quantum computer based on a single
molecule of 64 atoms would require covering a surface area (land and
water both) of 5,000 Earths with computers.

It's definitely out of date. I believe it was last year that a
mathematician whose name I can't remember figured out a way to crack
the key easily. Dunno if it's been implemented anywhere though.

I just checked my archived note file, and although I thought the
statement was interesting, I did not archive it. The subject may
have involved Blowfish as I was reading some msgs/articles on it
recently. I think Google led me too it but it was not what I
started my search effort for.

From you figures above, I will archive this msg because hacking
256 sounds like quite a stretch of the imagination. I do remember
they used the term 'hacking' and not 'breaking', if that could be
significant.
