Hi,

I'm developing a GTK+2 only frontend to several command line archivers
and 7zip is included. I would like to detect when a 7za archive
contains password protected files. I have the file 7zFormat.txt
included in the tar.gz package but is a bit difficult to understand at
least for me. I have been able to detect zip, rar and arj password
protected archives but not 7zip. Someone can help me to "decode" the
format so to understand at which position in the file I have to read to
know if the archive contains password protected archive ?

Thank you,
