It probably makes not too much sense zipping it again, but you could use

Code:
openssl enc

to encode the file with some cipher. The resulting key would serve as a password then. If it should indeed be compressed a second time just send it through gzip before. If your gzip refuses to cooperate (i could sympathize) use a stream:

Code:
cat file.gz | gzip > outfile.gz.gz

I hope this helps.

znew

ZNEW(1) 						    BSD General Commands Manual 						   ZNEW(1)

NAME

     znew -- convert compressed files to gzipped files

SYNOPSIS

     znew [-ftv9K] file ...

DESCRIPTION

     The znew utility uncompresses files compressed by compress(1) and recompresses them with gzip(1).

     The options are as follows:

     -f      Overwrite existing '.gz' files.  Unless this option is specified, znew refuses to overwrite existing files.

     -t      Test integrity of the gzipped file before deleting the original file.  If the integrity check fails, the original '.Z' file is not
	     removed.

     -v      Print a report specifying the achieved compression ratios.

     -9      Use the -9 mode of gzip(1), achieving better compression at the cost of slower execution.

     -K      Keep the original '.Z' file if it uses less disk blocks than the gzipped one.  A disk block is 1024 bytes.

SEE ALSO

     gzip(1)

CAVEATS

     The znew utility tries to maintain the file mode of the original file.  If the original file is not writable, it is not able to do that and
     znew will print a warning.
