Zip -E for Solaris 10?

Question

Hi, everyone
I have a need for what I think is an older version of info-zip that used to have the -E (capital E) option that would encrypt the file but it could be scripted unlike the current zip -e which will prompt you to enter a password twice and cannot be easily scripted. I need the -E version so code changes don't need to be made in production.
I can't seem to find this version of zip (source or binary) anywhere. Does anyone have any idea what happened to this option or where I might find the old source that contained this option?
TIA

Zip for Solaris 8 don't know -E.

Type 'zip -L' for the software License.
Zip 2.2 (November 3rd 1997). Usage:
zip [-options] [-b path] [-t mmddyyyy] [-n suffixes] [zipfile list] [-xi list]
  The default action is to add or replace zipfile entries from list, which
  can include the special name - to compress standard input.
  If zipfile and list are omitted, zip compresses stdin to stdout.
  -f   freshen: only changed files  -u   update: only changed or new files
  -d   delete entries in zipfile    -m   move into zipfile (delete files)
  -R   recurse into directories     -j   junk (don't record) directory names
  -0   store only                   -l   convert LF to CR LF (-ll CR LF to LF)
  -1   compress faster              -9   compress better
  -q   quiet operation              -v   verbose operation/print version info
  -c   add one-line comments        -z   add zipfile comment
  -@   read names from stdin        -o   make zipfile as old as latest entry
  -x   exclude the following names  -i   include only the following names
  -F   fix zipfile (-FF try harder) -D   do not add directory entries
  -A   adjust self-extracting exe   -J   junk zipfile prefix (unzipsfx)
  -T   test zipfile integrity       -X   eXclude eXtra file attributes
  -y   store symbolic links as the link instead of the referenced file
  -h   show this help               -n   don't compress these suffixes
# zip -E
zip error: Invalid command arguments (no such option: E)
# uname -a
SunOS XXXX 5.8 Generic_117350-34 sun4u sparc SUNW,Ultra-1
#Solaris binary compatible with previos version. So you can try just copy old zip to Solaris 10.
