CVD format</A>
</H2>
CVD (ClamAV Virus Database) is a digitally signed tarball file that
contains one or more databases. You can find some useful information in the
ASCII header of the file. It's a 512 bytes long string with the following
colon separated fields:
<PRE>
ClamAV-VDB:build time:version:number of signatures:functionality
level required:MD5 checksum:digital signature:builder name
</PRE>
and can be easily parsed by scripts or with <code>sigtool --info</code>.
There are two CVD databases in ClamAV: <I>main.cvd</I> and <I>daily.cvd</I>
for daily updates. You can use <I>sigtool</I> to unpack a CVD file
(<code>--unpack</code>) and to list virus names (<code>--list-sigs</code>). |
