If there is only one file after you extract the .tgz file, it
will probably be the file snakeoil2_070531.tar . This is the 
actual archive with the three files in it, so you need to 
open that file again in your archiver. Some archivers do
this in one go, others need two runs.

Here's some more info on the files:

sablo@BLOK /cygdrive/c/temp
$ file snakeoil2_070531.tgz
snakeoil2_070531.tgz: gzip compressed data, from Unix, last modified: Thu May 31 16:47:03 2007

sablo@BLOK /cygdrive/c/temp
$ gzip -d snakeoil2_070531.tgz

sablo@BLOK /cygdrive/c/temp
$ file snakeoil2_070531.tar
snakeoil2_070531.tar: POSIX tar archive (GNU)

sablo@BLOK /cygdrive/c/temp
$ tar xvf snakeoil2_070531.tar
rsasnakeoil2.README
rsasnakeoil2.cap
rsasnakeoil2.key

sablo@BLOK /cygdrive/c/temp
$ file rsasnakeoil2.*
rsasnakeoil2.README: ASCII text, with CRLF line terminators
rsasnakeoil2.cap:    tcpdump capture file (little-endian) - version 2.4 (Ethernet, capture length 65535)
rsasnakeoil2.key:    ASCII text, with CRLF line terminators

sablo@BLOK /cygdrive/c/temp
$

Hope this helps,
Cheers,
