+    \subsection{Passwords for archive files}

+    ClamAV 0.99 allows for users to specify password attempts for certain password-compatible archives.

+    Passwords will be attempted in order of appearance in the password signature file which use the extension

+    of \verb+.pwdb+. If no passwords apply or none are provided, ClamAV will default to the original

+    behavior of parsing the file.

+    Currently, as of ClamAV 0.99 [flevel 81], only \verb+.zip+ archives are supported.

+    The signature format is

+\begin{verbatim}

+SignatureName;TargetDescriptionBlock;PWStorageType;Password

+\end{verbatim}

+    where:

+    \begin{itemize}

+        \item \verb+SignatureName+: name to be displayed during debug when a password is successful

+        \item \verb+TargetDescriptionBlock+: provides information about the engine and target file with comma separated Arg:Val pairs

+        \begin{itemize}

+             \item \verb+Engine:X-Y+: Required engine functionality

+             \item \verb+Container:CL_TYPE_*+: File type of applicable containers

+        \end{itemize}

+        \item \verb+PWStorageType+: determines how the password field is parsed

+        \begin{itemize}

+            \item 0 = cleartext

+            \item 1 = hex

+        \end{itemize}

+        \item \verb+Password+: value used in password attempt

+    \end{itemize}

+    The signatures for password attempts are stored inside \verb+.pwdb+ files.
